+/**
+ * DOC: DEVICE_LIFESPAN
+ *
+ * The registering driver is the entity that allocates memory for the
+ * auxiliary_device and registers it on the auxiliary bus.  It is important to
+ * note that, as opposed to the platform bus, the registering driver is wholly
+ * responsible for the management of the memory used for the device object.
+ *
+ * To be clear the memory for the auxiliary_device is freed in the release()
+ * callback defined by the registering driver.  The registering driver should
+ * only call auxiliary_device_delete() and then auxiliary_device_uninit() when
+ * it is done with the device.  The release() function is then automatically
+ * called if and when other code releases their reference to the devices.
+ *
+ * A parent object, defined in the shared header file, contains the
+ * auxiliary_device.  It also contains a pointer to the shared object(s), which
+ * also is defined in the shared header.  Both the parent object and the shared
+ * object(s) are allocated by the registering driver.  This layout allows the
+ * auxiliary_driver's registering module to perform a container_of() call to go
+ * from the pointer to the auxiliary_device, that is passed during the call to
+ * the auxiliary_driver's probe function, up to the parent object, and then
+ * have access to the shared object(s).
+ *
+ * The memory for the shared object(s) must have a lifespan equal to, or
+ * greater than, the lifespan of the memory for the auxiliary_device.  The
+ * auxiliary_driver should only consider that the shared object is valid as
+ * long as the auxiliary_device is still registered on the auxiliary bus.  It
+ * is up to the registering driver to manage (e.g. free or keep available) the
+ * memory for the shared object beyond the life of the auxiliary_device.
+ *
+ * The registering driver must unregister all auxiliary devices before its own
+ * driver.remove() is completed.  An easy way to ensure this is to use the
+ * devm_add_action_or_reset() call to register a function against the parent
+ * device which unregisters the auxiliary device object(s).
+ *
+ * Finally, any operations which operate on the auxiliary devices must continue
+ * to function (if only to return an error) after the registering driver
+ * unregisters the auxiliary device.

+/**
+ * struct auxiliary_device - auxiliary device object.
+ * @dev: Device,
+ *       The release and parent fields of the device structure must be filled
+ *       in
+ * @name: Match name found by the auxiliary device driver,
+ * @id: unique identitier if multiple devices of the same name are exported,
+ *
+ * An auxiliary_device represents a part of its parent device's functionality.
+ * It is given a name that, combined with the registering drivers
+ * KBUILD_MODNAME, creates a match_name that is used for driver binding, and an
+ * id that combined with the match_name provide a unique name to register with
+ * the bus subsystem.  For example, a driver registering an auxiliary device is
+ * named 'foo_mod.ko' and the subdevice is named 'foo_dev'.  The match name is
+ * therefore 'foo_mod.foo_dev'.
+ *
+ * Registering an auxiliary_device is a three-step process.
+ *
+ * First, a 'struct auxiliary_device' needs to be defined or allocated for each
+ * sub-device desired.  The name, id, dev.release, and dev.parent fields of
+ * this structure must be filled in as follows.
+ *
+ * The 'name' field is to be given a name that is recognized by the auxiliary
+ * driver.  If two auxiliary_devices with the same match_name, eg
+ * "foo_mod.foo_dev", are registered onto the bus, they must have unique id
+ * values (e.g. "x" and "y") so that the registered devices names are
+ * "foo_mod.foo_dev.x" and "foo_mod.foo_dev.y".  If match_name + id are not
+ * unique, then the device_add fails and generates an error message.
+ *
+ * The auxiliary_device.dev.type.release or auxiliary_device.dev.release must
+ * be populated with a non-NULL pointer to successfully register the
+ * auxiliary_device.  This release call is where resources associated with the
+ * auxiliary device must be free'ed.  Because once the device is placed on the
+ * bus the parent driver can not tell what other code may have a reference to
+ * this data.
+ *
+ * The auxiliary_device.dev.parent should be set.  Typically to the registering
+ * drivers device.
+ *
+ * Second, call auxiliary_device_init(), which checks several aspects of the
+ * auxiliary_device struct and performs a device_initialize().  After this step
+ * completes, any error state must have a call to auxiliary_device_uninit() in
+ * its resolution path.
+ *
+ * The third and final step in registering an auxiliary_device is to perform a
+ * call to auxiliary_device_add(), which sets the name of the device and adds
+ * the device to the bus.
+ *
+ * .. code-block:: c
+ *
+ *      #define MY_DEVICE_NAME "foo_dev"
+ *
+ *      ...
+ *
+ *	struct auxiliary_device *my_aux_dev = my_aux_dev_alloc(xxx);
+ *
+ *	// Step 1:
+ *	my_aux_dev->name = MY_DEVICE_NAME;
+ *	my_aux_dev->id = my_unique_id_alloc(xxx);
+ *	my_aux_dev->dev.release = my_aux_dev_release;
+ *	my_aux_dev->dev.parent = my_dev;
+ *
+ *	// Step 2:
+ *	if (auxiliary_device_init(my_aux_dev))
+ *		goto fail;
+ *
+ *	// Step 3:
+ *	if (auxiliary_device_add(my_aux_dev)) {
+ *		auxiliary_device_uninit(my_aux_dev);
+ *		goto fail;
+ *	}
+ *
+ *	...
+ *
+ *
+ * Unregistering an auxiliary_device is a two-step process to mirror the
+ * register process.  First call auxiliary_device_delete(), then call
+ * auxiliary_device_uninit().
+ *
+ * .. code-block:: c

+/**
+ * struct comedi_subdevice - Working data for a COMEDI subdevice
+ * @device: COMEDI device to which this subdevice belongs.  (Initialized by
+ *	comedi_alloc_subdevices().)
+ * @index: Index of this subdevice within device's array of subdevices.
+ *	(Initialized by comedi_alloc_subdevices().)
+ * @type: Type of subdevice from &enum comedi_subdevice_type.  (Initialized by
+ *	the low-level driver.)
+ * @n_chan: Number of channels the subdevice supports.  (Initialized by the
+ *	low-level driver.)
+ * @subdev_flags: Various "SDF" flags indicating aspects of the subdevice to
+ *	the COMEDI core and user application.  (Initialized by the low-level
+ *	driver.)
+ * @len_chanlist: Maximum length of a channel list if the subdevice supports
+ *	asynchronous acquisition commands.  (Optionally initialized by the
+ *	low-level driver, or changed from 0 to 1 during post-configuration.)
+ * @private: Private data pointer which is either set by the low-level driver
+ *	itself, or by a call to comedi_alloc_spriv() which allocates storage.
+ *	In the latter case, the storage is automatically freed after the
+ *	low-level driver's "detach" handler is called for the device.
+ *	(Initialized by the low-level driver.)
+ * @async: Pointer to &struct comedi_async id the subdevice supports
+ *	asynchronous acquisition commands.  (Allocated and initialized during
+ *	post-configuration if needed.)
+ * @lock: Pointer to a file object that performed a %COMEDI_LOCK ioctl on the
+ *	subdevice.  (Initially NULL.)
+ * @busy: Pointer to a file object that is performing an asynchronous
+ *	acquisition command on the subdevice.  (Initially NULL.)
+ * @runflags: Internal flags for use by COMEDI core, mostly indicating whether
+ *	an asynchronous acquisition command is running.
+ * @spin_lock: Generic spin-lock for use by the COMEDI core and the low-level
+ *	driver.  (Initialized by comedi_alloc_subdevices().)
+ * @io_bits: Bit-mask indicating the channel directions for a DIO subdevice
+ *	with no more than 32 channels.  A '1' at a bit position indicates the
+ *	corresponding channel is configured as an output.  (Initialized by the
+ *	low-level driver for a DIO subdevice.  Forced to all-outputs during
+ *	post-configuration for a digital output subdevice.)
+ * @maxdata: If non-zero, this is the maximum raw data value of each channel.
+ *	If zero, the maximum data value is channel-specific.  (Initialized by
+ *	the low-level driver.)
+ * @maxdata_list: If the maximum data value is channel-specific, this points
+ *	to an array of maximum data values indexed by channel index.
+ *	(Initialized by the low-level driver.)
+ * @range_table: If non-NULL, this points to a COMEDI range table for the
+ *	subdevice.  If NULL, the range table is channel-specific.  (Initialized
+ *	by the low-level driver, will be set to an "invalid" range table during
+ *	post-configuration if @range_table and @range_table_list are both
+ *	NULL.)
+ * @range_table_list: If the COMEDI range table is channel-specific, this
+ *	points to an array of pointers to COMEDI range tables indexed by
+ *	channel number.  (Initialized by the low-level driver.)
+ * @chanlist: Not used.
+ * @insn_read: Optional pointer to a handler for the %INSN_READ instruction.
+ *	(Initialized by the low-level driver, or set to a default handler
+ *	during post-configuration.)
+ * @insn_write: Optional pointer to a handler for the %INSN_WRITE instruction.
+ *	(Initialized by the low-level driver, or set to a default handler
+ *	during post-configuration.)
+ * @insn_bits: Optional pointer to a handler for the %INSN_BITS instruction
+ *	for a digital input, digital output or digital input/output subdevice.
+ *	(Initialized by the low-level driver, or set to a default handler
+ *	during post-configuration.)
+ * @insn_config: Optional pointer to a handler for the %INSN_CONFIG
+ *	instruction.  (Initialized by the low-level driver, or set to a default
+ *	handler during post-configuration.)
+ * @do_cmd: If the subdevice supports asynchronous acquisition commands, this
+ *	points to a handler to set it up in hardware.  (Initialized by the
+ *	low-level driver.)
+ * @do_cmdtest: If the subdevice supports asynchronous acquisition commands,
+ *	this points to a handler used to check and possibly tweak a prospective
+ *	acquisition command without setting it up in hardware.  (Initialized by
+ *	the low-level driver.)
+ * @poll: If the subdevice supports asynchronous acquisition commands, this
+ *	is an optional pointer to a handler for the %COMEDI_POLL ioctl which
+ *	instructs the low-level driver to synchronize buffers.  (Initialized by
+ *	the low-level driver if needed.)
+ * @cancel: If the subdevice supports asynchronous acquisition commands, this
+ *	points to a handler used to terminate a running command.  (Initialized
+ *	by the low-level driver.)
+ * @buf_change: If the subdevice supports asynchronous acquisition commands,
+ *	this is an optional pointer to a handler that is called when the data
+ *	buffer for handling asynchronous commands is allocated or reallocated.
+ *	(Initialized by the low-level driver if needed.)
+ * @munge: If the subdevice supports asynchronous acquisition commands and
+ *	uses DMA to transfer data from the hardware to the acquisition buffer,
+ *	this points to a function used to "munge" the data values from the
+ *	hardware into the format expected by COMEDI.  (Initialized by the
+ *	low-level driver if needed.)
+ * @async_dma_dir: If the subdevice supports asynchronous acquisition commands
+ *	and uses DMA to transfer data from the hardware to the acquisition
+ *	buffer, this sets the DMA direction for the buffer. (initialized to
+ *	%DMA_NONE by comedi_alloc_subdevices() and changed by the low-level
+ *	driver if necessary.)
+ * @state: Handy bit-mask indicating the output states for a DIO or digital
+ *	output subdevice with no more than 32 channels. (Initialized by the
+ *	low-level driver.)
+ * @class_dev: If the subdevice supports asynchronous acquisition commands,
+ *	this points to a sysfs comediX_subdY device where X is the minor device
+ *	number of the COMEDI device and Y is the subdevice number.  The minor
+ *	device number for the sysfs device is allocated dynamically in the
+ *	range 48 to 255.  This is used to allow the COMEDI device to be opened
+ *	with a different default read or write subdevice.  (Allocated during
+ *	post-configuration if needed.)
+ * @minor: If @class_dev is set, this is its dynamically allocated minor
+ *	device number.  (Set during post-configuration if necessary.)
+ * @readback: Optional pointer to memory allocated by
+ *	comedi_alloc_subdev_readback() used to hold the values written to
+ *	analog output channels so they can be read back.  The storage is
+ *	automatically freed after the low-level driver's "detach" handler is
+ *	called for the device.  (Initialized by the low-level driver.)
+ *
+ * This is the main control structure for a COMEDI subdevice.  If the subdevice
+ * supports asynchronous acquisition commands, additional information is stored
+ * in the &struct comedi_async pointed to by @async.
+ *
+ * Most of the subdevice is initialized by the low-level driver's "attach" or
+ * "auto_attach" handlers but parts of it are initialized by
+ * comedi_alloc_subdevices(), and other parts are initialized during
+ * post-configuration on return from that handler.
+ *
+ * A low-level driver that sets @insn_bits for a digital input, digital output,
+ * or DIO subdevice may leave @insn_read and @insn_write uninitialized, in
+ * which case they will be set to a default handler during post-configuration
+ * that uses @insn_bits to emulate the %INSN_READ and %INSN_WRITE instructions.

+ *   Buf_Write_Count <= Buf_Write_Alloc_Count <=
+ *   (Buf_Read_Count + prealloc_bufsz)

+ * (Those aren't the actual members, apart from prealloc_bufsz.) When the
+ * buffer is reset, those _Count values start at 0 and only increase in value,
+ * maintaining the above inequalities until the next time the buffer is
+ * reset.  The buffer is divided into the following regions by the inequalities:
+ *
+ *   [0, Buf_Read_Count):
+ *     old region no longer accessible
+ *
+ *   [Buf_Read_Count, Buf_Read_Alloc_Count):
+ *     filled and munged region allocated for reading but not yet read
+ *
+ *   [Buf_Read_Alloc_Count, Munge_Count):

+ *
+ *   [Munge_Count, Buf_Write_Count):

+ *     unfilled region not yet allocated for writing
+ *
+ *   [Buf_Read_Count + prealloc_bufsz, infinity):
+ *     unfilled region not yet accessible
+ *
+ * Data needs to be written into the buffer before it can be read out,
+ * and may need to be converted (or "munged") between the two
+ * operations.  Extra unfilled buffer space may need to allocated for
+ * writing (advancing Buf_Write_Alloc_Count) before new data is written.
+ * After writing new data, the newly filled space needs to be released
+ * (advancing Buf_Write_Count).  This also results in the new data being
+ * "munged" (advancing Munge_Count).  Before data is read out of the
+ * buffer, extra space may need to be allocated for reading (advancing
+ * Buf_Read_Alloc_Count).  After the data has been read out, the space
+ * needs to be released (advancing Buf_Read_Count).
+ *
+ * The actual members, buf_read_count, buf_read_alloc_count,
+ * munge_count, buf_write_count, and buf_write_alloc_count take the
+ * value of the corresponding capitalized _Count values modulo 2^32
+ * (UINT_MAX+1).  Subtracting a "higher" _count value from a "lower"
+ * _count value gives the same answer as subtracting a "higher" _Count
+ * value from a lower _Count value because prealloc_bufsz < UINT_MAX+1.
+ * The modulo operation is done implicitly.
+ *
+ * The buf_read_ptr, munge_ptr, and buf_write_ptr members take the value
+ * of the corresponding capitalized _Count values modulo prealloc_bufsz.
+ * These correspond to byte indices in the physical buffer.  The modulo

- * @FAULT_FLAG_INTERRUPTIBLE: The fault can be interrupted by non-fatal signals.
- *
- * About @FAULT_FLAG_ALLOW_RETRY and @FAULT_FLAG_TRIED: we can specify
- * whether we would allow page faults to retry by specifying these two
- * fault flags correctly.  Currently there can be three legal combinations:
- *
- * (a) ALLOW_RETRY and !TRIED:  this means the page fault allows retry, and
- *                              this is the first try
- *
- * (b) ALLOW_RETRY and TRIED:   this means the page fault allows retry, and
- *                              we've already tried at least once
- *
- * (c) !ALLOW_RETRY and !TRIED: this means the page fault does not allow retry
- *
- * The unlisted combination (!ALLOW_RETRY && TRIED) is illegal and should never
- * be used.  Note that page faults can be allowed to retry for multiple times,
- * in which case we'll have an initial fault with flags (a) then later on
- * continuous faults with flags (b).  We should always try to detect pending
- * signals before a retry to make sure the continuous page faults can still be
- * interrupted if necessary.

+ * @energy_full_design_uwh: energy content when fully charged in microwatt
+ *   hours
+ * @charge_full_design_uah: charge content when fully charged in microampere
+ *   hours
+ * @voltage_min_design_uv: minimum voltage across the poles when the battery
+ *   is at minimum voltage level in microvolts. If the voltage drops below this
+ *   level the battery will need precharging when using CC/CV charging.
+ * @voltage_max_design_uv: voltage across the poles when the battery is fully
+ *   charged in microvolts. This is the "nominal voltage" i.e. the voltage
+ *   printed on the label of the battery.
+ * @tricklecharge_current_ua: the tricklecharge current used when trickle
+ *   charging the battery in microamperes. This is the charging phase when the
+ *   battery is completely empty and we need to carefully trickle in some
+ *   charge until we reach the precharging voltage.
+ * @precharge_current_ua: current to use in the precharge phase in microamperes,
+ *   the precharge rate is limited by limiting the current to this value.
+ * @precharge_voltage_max_uv: the maximum voltage allowed when precharging in
+ *   microvolts. When we pass this voltage we will nominally switch over to the
+ *   CC (constant current) charging phase defined by constant_charge_current_ua
+ *   and constant_charge_voltage_max_uv.
+ * @charge_term_current_ua: when the current in the CV (constant voltage)
+ *   charging phase drops below this value in microamperes the charging will
+ *   terminate completely and not restart until the voltage over the battery
+ *   poles reach charge_restart_voltage_uv unless we use maintenance charging.
+ * @charge_restart_voltage_uv: when the battery has been fully charged by
+ *   CC/CV charging and charging has been disabled, and the voltage subsequently
+ *   drops below this value in microvolts, the charging will be restarted
+ *   (typically using CV charging).
+ * @overvoltage_limit_uv: If the voltage exceeds the nominal voltage
+ *   voltage_max_design_uv and we reach this voltage level, all charging must
+ *   stop and emergency procedures take place, such as shutting down the system
+ *   in some cases.
+ * @constant_charge_current_max_ua: current in microamperes to use in the CC
+ *   (constant current) charging phase. The charging rate is limited
+ *   by this current. This is the main charging phase and as the current is
+ *   constant into the battery the voltage slowly ascends to
+ *   constant_charge_voltage_max_uv.
+ * @constant_charge_voltage_max_uv: voltage in microvolts signifying the end of
+ *   the CC (constant current) charging phase and the beginning of the CV
+ *   (constant voltage) charging phase.
+ * @factory_internal_resistance_uohm: the internal resistance of the battery
+ *   at fabrication time, expressed in microohms. This resistance will vary
+ *   depending on the lifetime and charge of the battery, so this is just a
+ *   nominal ballpark figure.
+ * @ocv_temp: array indicating the open circuit voltage (OCV) capacity
+ *   temperature indices. This is an array of temperatures in degrees Celsius
+ *   indicating which capacity table to use for a certain temperature, since
+ *   the capacity for reasons of chemistry will be different at different
+ *   temperatures. Determining capacity is a multivariate problem and the
+ *   temperature is the first variable we determine.
+ * @temp_ambient_alert_min: the battery will go outside of operating conditions
+ *   when the ambient temperature goes below this temperature in degrees
+ *   Celsius.
+ * @temp_ambient_alert_max: the battery will go outside of operating conditions
+ *   when the ambient temperature goes above this temperature in degrees
+ *   Celsius.
+ * @temp_alert_min: the battery should issue an alert if the internal
+ *   temperature goes below this temperature in degrees Celsius.
+ * @temp_alert_max: the battery should issue an alert if the internal
+ *   temperature goes above this temperature in degrees Celsius.
+ * @temp_min: the battery will go outside of operating conditions when
+ *   the internal temperature goes below this temperature in degrees Celsius.
+ *   Normally this means the system should shut down.
+ * @temp_max: the battery will go outside of operating conditions when
+ *   the internal temperature goes above this temperature in degrees Celsius.
+ *   Normally this means the system should shut down.
+ * @ocv_table: for each entry in ocv_temp there is a corresponding entry in
+ *   ocv_table and a size for each entry in ocv_table_size. These arrays
+ *   determine the capacity in percent in relation to the voltage in microvolts
+ *   at the indexed temperature.
+ * @ocv_table_size: for each entry in ocv_temp this array is giving the size of
+ *   each entry in the array of capacity arrays in ocv_table.
+ * @resist_table: this is a table that correlates a battery temperature to the
+ *   expected internal resistance at this temperature. The resistance is given
+ *   as a percentage of factory_internal_resistance_uohm. Knowing the
+ *   resistance of the battery is usually necessary for calculating the open
+ *   circuit voltage (OCV) that is then used with the ocv_table to calculate
+ *   the capacity of the battery. The resist_table must be ordered descending
+ *   by temperature: highest temperature with lowest resistance first, lowest
+ *   temperature with highest resistance last.
+ * @resist_table_size: the number of items in the resist_table.
+ *
  * This is the recommended struct to manage static battery parameters,
  * populated by power_supply_get_battery_info(). Most platform drivers should
  * use these for consistency.
+ *
  * Its field names must correspond to elements in enum power_supply_property.
  * The default field value is -EINVAL.
- * Power supply class itself doesn't use this.

+ * The charging parameters here assume a CC/CV charging scheme. This method
+ * is most common with Lithium Ion batteries (other methods are possible) and
+ * looks as follows:
+ *
+ * ^ Battery voltage
+ * |                                               --- overvoltage_limit_uv

+ * |.... tricklecharge_current_ua            .
+ * |                                         .
+ * +-----------------------------------------------------------------> time
+ *
+ * These diagrams are synchronized on time and the voltage and current
+ * follow each other.
+ *
+ * With CC/CV charging commence over time like this for an empty battery:
+ *
+ * 1. When the battery is completely empty it may need to be charged with
+ *    an especially small current so that electrons just "trickle in",
+ *    this is the tricklecharge_current_ua.
+ *
+ * 2. Next a small initial pre-charge current (precharge_current_ua)
+ *    is applied if the voltage is below precharge_voltage_max_uv until we
+ *    reach precharge_voltage_max_uv. CAUTION: in some texts this is referred
+ *    to as "trickle charging" but the use in the Linux kernel is different
+ *    see below!
+ *
+ * 3. Then the main charging current is applied, which is called the constant
+ *    current (CC) phase. A current regulator is set up to allow
+ *    constant_charge_current_max_ua of current to flow into the battery.
+ *    The chemical reaction in the battery will make the voltage go up as
+ *    charge goes into the battery. This current is applied until we reach
+ *    the constant_charge_voltage_max_uv voltage.
+ *
+ * 4. At this voltage we switch over to the constant voltage (CV) phase. This
+ *    means we allow current to go into the battery, but we keep the voltage
+ *    fixed. This current will continue to charge the battery while keeping
+ *    the voltage the same. A chemical reaction in the battery goes on
+ *    storing energy without affecting the voltage. Over time the current
+ *    will slowly drop and when we reach charge_term_current_ua we will
+ *    end the constant voltage phase.
+ *
+ * After this the battery is fully charged, and if we do not support maintenance
+ * charging, the charging will not restart until power dissipation makes the
+ * voltage fall so that we reach charge_restart_voltage_uv and at this point
+ * we restart charging at the appropriate phase, usually this will be inside
+ * the CV phase.
+ *
+ * If we support maintenance charging the voltage is however kept high after
+ * the CV phase with a very low current. This is meant to let the same charge
+ * go in for usage while the charger is still connected, mainly for
+ * dissipation for the power consuming entity while connected to the
+ * charger.
+ *
+ * All charging MUST terminate if the overvoltage_limit_uv is ever reached.
+ * Overcharging Lithium Ion cells can be DANGEROUS and lead to fire or
+ * explosions.
+ *
+ * The power supply class itself doesn't use this struct as of now.

+ *	Requests the tty layer to reset the termios setting when the last
+ *	process has closed the device. Used for PTYs, in particular.
+ *
+ * TTY_DRIVER_REAL_RAW
+ *	Indicates that the driver will guarantee not to set any special
+ *	character handling flags if this is set for the tty:
+ *
+ *	``(IGNBRK || (!BRKINT && !PARMRK)) && (IGNPAR || !INPCK)``
+ *
+ *	That is, if there is no reason for the driver to
+ *	send notifications of parity and break characters up to the line
+ *	driver, it won't do so.  This allows the line driver to optimize for
+ *	this case if this flag is set.  (Note that there is also a promise, if
+ *	the above case is true, not to signal overruns, either.)
+ *
+ * TTY_DRIVER_DYNAMIC_DEV
+ *	The individual tty devices need to be registered with a call to
+ *	tty_register_device() when the device is found in the system and
+ *	unregistered with a call to tty_unregister_device() so the devices will
+ *	be show up properly in sysfs.  If not set, all &tty_driver.num entries
+ *	will be created by the tty core in sysfs when tty_register_driver() is
+ *	called.  This is to be used by drivers that have tty devices that can
+ *	appear and disappear while the main tty driver is registered with the
+ *	tty core.
+ *
+ * TTY_DRIVER_DEVPTS_MEM
+ *	Don't use the standard arrays (&tty_driver.ttys and
+ *	&tty_driver.termios), instead use dynamic memory keyed through the
+ *	devpts filesystem. This is only applicable to the PTY driver.
+ *
+ * TTY_DRIVER_HARDWARE_BREAK
+ *	Hardware handles break signals. Pass the requested timeout to the
+ *	&tty_operations.break_ctl instead of using a simple on/off interface.
+ *
+ * TTY_DRIVER_DYNAMIC_ALLOC
+ *	Do not allocate structures which are needed per line for this driver
+ *	(&tty_driver.ports) as it would waste memory. The driver will take
+ *	care. This is only applicable to the PTY driver.
+ *
+ * TTY_DRIVER_UNNUMBERED_NODE
+ *	Do not create numbered ``/dev`` nodes. For example, create
+ *	``/dev/ttyprintk`` and not ``/dev/ttyprintk0``. Applicable only when a
+ *	driver for a single tty device is being allocated.

+ * "struct bpf_core_relo" is used to pass relocation data form LLVM to libbpf

+ *
+ * CO-RE relocation captures the following data:
+ * - insn_off - instruction offset (in bytes) within a BPF program that needs
+ *   its insn->imm field to be relocated with actual field info;
+ * - type_id - BTF type ID of the "root" (containing) entity of a relocatable
+ *   type or field;
+ * - access_str_off - offset into corresponding .BTF string section. String
+ *   interpretation depends on specific relocation kind:
+ *     - for field-based relocations, string encodes an accessed field using
+ *       a sequence of field and array indices, separated by colon (:). It's
+ *       conceptually very close to LLVM's getelementptr ([0]) instruction's
+ *       arguments for identifying offset to a field.
+ *     - for type-based relocations, strings is expected to be just "0";
+ *     - for enum value-based relocations, string contains an index of enum
+ *       value within its enum type;
+ * - kind - one of enum bpf_core_relo_kind;
+ *
+ * Example:
+ *   struct sample {
+ *       int a;
+ *       struct {
+ *           int b[10];
+ *       };
+ *   };
+ *
+ *   struct sample *s = ...;
+ *   int *x = &s->a;     // encoded as "0:0" (a is field #0)
+ *   int *y = &s->b[5];  // encoded as "0:1:0:5" (anon struct is field #1,
+ *                       // b is field #0 inside anon struct, accessing elem #5)
+ *   int *z = &s[10]->b; // encoded as "10:1" (ptr is used as an array)
+ *
+ * type_id for all relocs in this example will capture BTF type id of
+ * `struct sample`.
+ *
+ * Such relocation is emitted when using __builtin_preserve_access_index()
+ * Clang built-in, passing expression that captures field address, e.g.:
+ *
+ * bpf_probe_read(&dst, sizeof(dst),
+ *		  __builtin_preserve_access_index(&src->a.b.c));
+ *
+ * In this case Clang will emit field relocation recording necessary data to
+ * be able to find offset of embedded `a.b.c` field within `src` struct.

+ *
+ * NOTE ABOUT THE CHOICE OF NAMES HERE AND THE CAMELSCRIPT:
+ *   The choice to use CamelScript and the exact names below is for
+ *   maintainability, clarity, similarity to manufacturer's documentation,
+ *   _and_ a mitigation for confusion that has plagued the use of these drivers
+ *   for years!
+ *
+ *   More detail:
+ *   There have been significant confusions over the past many years for users
+ *   when trying to understand how to connect to/from signals and terminals on
+ *   NI hardware using comedi.  The major reason for this is that the actual
+ *   register values were exposed and required to be used by users.  Several
+ *   major reasons exist why this caused major confusion for users:
+ *   1) The register values are _NOT_ in user documentation, but rather in
+ *     arcane locations, such as a few register programming manuals that are
+ *     increasingly hard to find and the NI MHDDK (comments in example code).
+ *     There is no one place to find the various valid values of the registers.
+ *   2) The register values are _NOT_ completely consistent.  There is no way to
+ *     gain any sense of intuition of which values, or even enums one should use
+ *     for various registers.  There was some attempt in prior use of comedi to
+ *     name enums such that a user might know which enums should be used for
+ *     varying purposes, but the end-user had to gain a knowledge of register
+ *     values to correctly wield this approach.
+ *   3) The names for signals and registers found in the various register level
+ *     programming manuals and vendor-provided documentation are _not_ even
+ *     close to the same names that are in the end-user documentation.
+ *
+ *   Similar, albeit less, confusion plagued NI's previous version of their own
+ *   drivers.  Earlier than 2003, NI greatly simplified the situation for users
+ *   by releasing a new API that abstracted the names of signals/terminals to a
+ *   common and intuitive set of names.
+ *
+ *   The names below mirror the names chosen and well documented by NI.  These
+ *   names are exposed to the user via the comedilib user library.  By keeping
+ *   the names below, in spite of the use of CamelScript, maintenance will be
+ *   greatly eased and confusion for users _and_ comedi developers will be
+ *   greatly reduced.

+/*
+ * Detailed Interface Description
+ * ==============================
+ * The pvUSB interface is using a split driver design: a frontend driver in
+ * the guest and a backend driver in a driver domain (normally dom0) having
+ * access to the physical USB device(s) being passed to the guest.
+ *
+ * The frontend and backend drivers use XenStore to initiate the connection
+ * between them, the I/O activity is handled via two shared ring pages and an
+ * event channel. As the interface between frontend and backend is at the USB
+ * host connector level, multiple (up to 31) physical USB devices can be
+ * handled by a single connection.
+ *
+ * The Xen pvUSB device name is "qusb", so the frontend's XenStore entries are
+ * to be found under "device/qusb", while the backend's XenStore entries are
+ * under "backend/<guest-dom-id>/qusb".
+ *
+ * When a new pvUSB connection is established, the frontend needs to setup the
+ * two shared ring pages for communication and the event channel. The ring
+ * pages need to be made available to the backend via the grant table
+ * interface.
+ *
+ * One of the shared ring pages is used by the backend to inform the frontend
+ * about USB device plug events (device to be added or removed). This is the
+ * "conn-ring".
+ *
+ * The other ring page is used for USB I/O communication (requests and
+ * responses). This is the "urb-ring".
+ *
+ * Feature and Parameter Negotiation
+ * =================================
+ * The two halves of a Xen pvUSB driver utilize nodes within the XenStore to
+ * communicate capabilities and to negotiate operating parameters. This
+ * section enumerates these nodes which reside in the respective front and
+ * backend portions of the XenStore, following the XenBus convention.
+ *
+ * Any specified default value is in effect if the corresponding XenBus node
+ * is not present in the XenStore.
+ *
+ * XenStore nodes in sections marked "PRIVATE" are solely for use by the
+ * driver side whose XenBus tree contains them.

+ *-------------------------- USB device plug events --------------------------
+ *
+ * USB device plug events are send via the "conn-ring" shared page. As only
+ * events are being sent, the respective requests from the frontend to the
+ * backend are just dummy ones.
+ * The events sent to the frontend have the following layout:
+ *         0                1                 2               3        octet

+ *   id - uint16_t, event id (taken from the actual frontend dummy request)
+ *   portnum - uint8_t, port number (1 ... 31)
