USB-serial fixes for 5.16-rc3
Here's a fix for a pl2303 type-detection issue and some new modem
devices ids.
All but the last commit have been in linux-next, and with no reported
issues.

Update the USB serial option driver support for the Fibocom
FM101-GL Cat.6
LTE modules as there are actually several different variants.
- VID:PID 2cb7:01a2, FM101-GL are laptop M.2 cards (with
MBIM interfaces for /Linux/Chrome OS)
- VID:PID 2cb7:01a4, FM101-GL for laptop debug M.2 cards(with adb
interface for /Linux/Chrome OS)

Fix the circular lock dependency and unbalanced unlock of addess0_mutex
introduced when fixing an address0_mutex enumeration retry race in commit
ae6dc22d2d1 ("usb: hub: Fix usb enumeration issue due to address0 race")
Make sure locking order between port_dev->status_lock and address0_mutex
is correct, and that address0_mutex is not unlocked in hub_port_connect
"done:" codepath which may be reached without locking address0_mutex

At least some PL2303GC have a bcdDevice of 0x105 instead of 0x100 as the
datasheet claims. Add it to the list of known release numbers for the
HXN (G) type.
Note the chip type could only be determined indirectly based on its
package being of QFP type, which appears to only be available for
PL2303GC.

If the first call to devm_usb_get_phy_by_phandle(dev, "fsl,usbphy", 0)
fails with something other than -ENODEV then it leads to an error
pointer dereference. For those errors we should just jump directly to

The address0_mutex exists to prevent this across both xhci roothubs.
If hub_port_init() fails, it may unlock the mutex and exit with a xhci
slot in default state. If the other xhci roothub calls hub_port_init()
at this point we end up with two slots in default state.
Make sure the address0_mutex protects the slot default state across
hub_port_init() retries, until slot is addressed or disabled.
Note, one known minor case is not fixed by this patch.
If device needs to be reset during resume, but fails all hub_port_init()
retries in usb_reset_and_verify_device(), then it's possible the slot is
still left in default state when address0_mutex is unlocked.

The code that enables either BC_LVL or COMP_CHNG interrupt in tcpm_set_cc
wrongly assumes that the interrupt is unmasked by writing 1 to the apropriate
bit in the mask register. In fact, interrupts are enabled when the mask
is 0, so the tcpm_set_cc enables interrupt for COMP_CHNG when it expects
BC_LVL interrupt to be enabled.
This causes inability of the driver to recognize cable unplug events
in host mode (unplug is recognized only via a COMP_CHNG interrupt).
In device mode this bug was masked by simultaneous triggering of the VBUS
change interrupt, because of loss of VBUS when the port peer is providing
power.

A new commit in LLVM causes an error on the use of 'long double' when
'-mno-x87' is used, which the kernel does through an alias,
'-mno-80387' (see the LLVM commit below for more details around why it
does this).
drivers/usb/dwc2/hcd_queue.c:1744:25: error: expression requires 'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
delay = ktime_set(0, DWC2_RETRY_WAIT_DELAY);
^
drivers/usb/dwc2/hcd_queue.c:62:34: note: expanded from macro 'DWC2_RETRY_WAIT_DELAY'
#define DWC2_RETRY_WAIT_DELAY (1 * 1E6L)
^
1 error generated.
This happens due to the use of a 'long double' literal. The 'E6' part of
'1E6L' causes the literal to be a 'double' then the 'L' suffix promotes
it to 'long double'.
There is no visible reason for a floating point value in this driver, as
the value is only used as a parameter to a function that expects an
integer type. Use NSEC_PER_MSEC, which is the same integer value as
'1E6L', to avoid changing functionality but fix the error.

Added updating of request frame number for elapsed frames,

This will allow function driver to correctly track frames in
case of Missed ISOC occurs.
Added setting request actual length to 0 for elapsed frames.
In Slave mode when pushing data to RxFIFO by dwords, request
actual length incrementing accordingly. But before whole packet
will be pushed into RxFIFO and send to host can occurs Missed
ISOC and data will not send to host. So, in this case request
actual length should be reset to 0.

The programming guide noted that the driver needs to verify if the link
state is in U0 before executing the Start Transfer command. If it's not
in U0, the driver needs to perform remote wakeup. This is not accurate.
If the link state is in U1/U2, then the controller will not respond to
link recovery request from DCTL.ULSTCHNGREQ. The Start Transfer command
will trigger a link recovery if it is in U1/U2. A clarification will be
added to the programming guide for all controller versions.
The current implementation shouldn't cause any functional issue. It may
occasionally report an invalid time out warning from failed link
recovery request. The driver will still go ahead with the Start Transfer
command if the remote wakeup fails. The new change only initiates remote
wakeup where it is needed, which is when the link state is in L1/L2/U3.

The End Transfer command from a stream endpoint will generate a NoStream
event, and we should ignore it. Currently we set the flag
DWC3_EP_IGNORE_NEXT_NOSTREAM to track this prior to sending the command,
and it will be cleared on the next stream event. However, a stream event
may be generated before the End Transfer command completion and
prematurely clear the flag. Fix this by setting the flag on End Transfer
completion instead.

Some USB 3.1 enumeration issues were reported after the hub driver removed
the minimum 100ms limit for the power-on-good delay.
Since commit 90d28fb53d4a ("usb: core: reduce power-on-good delay time of
root hub") the hub driver sets the power-on-delay based on the
bPwrOn2PwrGood value in the hub descriptor.
xhci driver has a 20ms bPwrOn2PwrGood value for both roothubs based
on xhci spec section 5.4.8, but it's clearly not enough for the
USB 3.1 devices, causing enumeration issues.
Tests indicate full 100ms delay is needed.

When receiving a disconnect event from the UDC, the mass storage
function driver currently runs the handle_exception() routine
asynchronously. For UDCs that support runtime PM, there is a
possibility the UDC is already suspended by the time the
do_set_interface() is executed. This can lead to HW register access
while the UDC is already suspended.

The usb_ep_disable() and usb_ep_enable() routines are being widely

not be true. Add an explicit comment mentioning that it can be used

If keyspan_port_probe() fails to allocate memory for an out_buffer[i] or
in_buffer[i], the previously allocated memory for out_buffer or
in_buffer needs to be freed on the error handling path, otherwise a
memory leak will result.

The new wrapper functions for usb_control_msg() can accept data from
stack and treat short reads as errors. Hence use the wrappers functions.
Please note that because of this change, cp210x_read_reg_block() will no
longer log the length of short reads.

usb_control_msg_recv() is a new wrapper function for usb_control_msg()
that has error checks for short reads. This function also accepts data
buffer on stack. Hence use this function to simplify error handling for
short reads. Short reads will now get reported as -EREMOTEIO with no
indication of how short the transfer was.

USB control-message timeouts are specified in milliseconds and should
specifically not vary with CONFIG_HZ.
Use the common control-message timeout define for the five-second
timeout and drop the driver-specific one.

The second argument was only used by the USB gadget code, yet everyone
pays the overhead of passing a zero to be passed into aio, where it
ends up being part of the aio res2 value.
Now that everybody is passing in zero, kill off the extra argument.

The USB gadget code is the only code that every tried to utilize the
2nd argument of the aio completions, but there are strong suspicions
that it was never actually used by anything on the userspace side.
Out of the 3 cases that touch it, two of them just pass in the same
as res, and the last one passes in error/transfer in res like any
other normal use case.
Remove the 2nd argument, pass 0 like the rest of the in-kernel users
of kiocb based IO.

STM32MP15 complies with the OTG 2.0. Set OTG revision accordingly. It is
useful for the of_usb_update_otg_caps() routine to check and update
otg_rev to the lower value between DT and provided params.

Currently the dwc2 doesn't fill in the 'otg_caps' of usb_gadget structure.
When registering a gadget device (e.g. via configfs), the
usb_otg_descriptor_init() checks the 'otg_caps' and 'otg_rev'. It defaults
to HNP and SRP bmAttributes if unspecified. There may be a mismatch with
what's being set in dwc2 params structure. This result in the descriptors
to be miss-configured in this case.
So replace 'otg_cap' bit field by 'otg_caps' structure, so hnp, srp and
otg_rev' can be configured directly in the params.
It's then provided to the gadget struct. These parameters can be tuned
for each platform. In case it's not set, it will default to current
behavior.
Also add option to setup these from the device tree by calling
of_usb_update_otg_caps(). This provides support for standard properties
such as "otg-rev", "hnp-disable" and "srp-disable" (see usb-drd.yaml).

This patch adds the fields UVC_STREAM_PTS and UVC_STREAM_SCR to the uvc
header, in case this data is available. It also enables the copy of the
timestamp to the vb2_v4l2_buffer by setting V4L2_BUF_FLAG_TIMESTAMP_COPY
in the queue.timestamp_flags.

The function uvc_video_encode_header function returns the number of
bytes used for the header. We change the video_encode_isoc_sg function
to use the returned header_len rather than UVCG_REQUEST_HEADER_LEN and
make the encode function more flexible.

The u_audio param fb_max was not set to its default value in f_uac1.c.
As a result the maximum value of Playback Pitch ctl was kept at 1000000,
not allowing to set faster playback pitch for UAC1.
The setting required moving the default constant UAC2_DEF_FB_MAX from
u_uac2.h to FBACK_FAST_MAX in u_audio.h as that header is common for
f_uac1.c and f_uac2.c.
