The default device address apparently comes from the NVM configuration
file and can differ quite a bit between controllers.
Store the default address when parsing the configuration file and use it
to determine whether the controller has been provisioned with an
address.
This makes sure that devices without a unique address start as
unconfigured unless a valid address has been provided in the devicetree.

The NVM configuration files used by WCN3988 and WCN3990/1/8 have two
sets of configuration tags that are enclosed by a type-length header of
type four which the current parser fails to account for.
Instead the driver happily parses random data as if it were valid tags,
something which can lead to the configuration data being corrupted if it
ever encounters the words 0x0011 or 0x001b.
As is clear from commit b63882549b2b ("Bluetooth: btqca: Fix the NVM
baudrate tag offcet for wcn3991") the intention has always been to
process the configuration data also for WCN3991 and WCN3998 which
encodes the baud rate at a different offset.
Fix the parser so that it can handle the WCN3xxx configuration files,
which has an enclosing type-length header of type four and two sets of
TLV tags enclosed by a type-length header of type two and three,
respectively.
Note that only the first set, which contains the tags the driver is
currently looking for, will be parsed for now.
With the parser fixed, the software in-band sleep bit will now be set
for WCN3991 and WCN3998 (as it is for later controllers) and the default
baud rate 3200000 may be updated by the driver also for WCN3xxx
controllers.
Notably the deep-sleep feature bit is already set by default in all
configuration files in linux-firmware.

Qualcomm Bluetooth controllers may not have been provisioned with a
valid device address and instead end up using the default address
00:00:00:00:5a:ad.
This address is now used to determine if a controller has a valid
address or if one needs to be provided through devicetree or by user
space before the controller can be used.
It turns out that the WCN3991 controllers used in Chromium Trogdor
machines use a different default address, 39:98:00:00:5a:ad, which also
needs to be marked as invalid so that the correct address is fetched
from the devicetree.
Qualcomm has unfortunately not yet provided any answers as to whether
the 39:98 encodes a hardware id and if there are other variants of the
default address that needs to be handled by the driver.
For now, add the Trogdor WCN3991 default address to the device address
check to avoid having these controllers start with the default address
instead of their assigned addresses.

Qualcomm Bluetooth controllers may not have been provisioned with a
valid device address and instead end up using the default address
00:00:00:00:5a:ad.
This was previously believed to be due to lack of persistent storage for
the address but it may also be due to integrators opting to not use the
on-chip OTP memory and instead store the address elsewhere (e.g. in
storage managed by secure world firmware).
According to Qualcomm, at least WCN6750, WCN6855 and WCN7850 have
on-chip OTP storage for the address.
As the device type alone cannot be used to determine when the address is
valid, instead read back the address during setup() and only set the
HCI_QUIRK_USE_BDADDR_PROPERTY flag when needed.
This specifically makes sure that controllers that have been provisioned
with an address do not start as unconfigured.

The WCN6855 firmware on the Lenovo ThinkPad X13s expects the Bluetooth
device address in big-endian order when setting it using the
EDL_WRITE_BD_ADDR_OPCODE command.
Presumably, this is the case for all non-ROME devices which all use the
EDL_WRITE_BD_ADDR_OPCODE command for this (unlike the ROME devices which
use a different command and expect the address in little-endian order).
Reverse the little-endian address before setting it to make sure that
the address can be configured using tools like btmgmt or using the
'local-bd-address' devicetree property.
Note that this can potentially break systems with boot firmware which
has started relying on the broken behaviour and is incorrectly passing
the address via devicetree in big-endian order.
The only device affected by this should be the WCN3991 used in some
Chromebooks. As ChromeOS updates the kernel and devicetree in lockstep,
the new 'qcom,local-bd-address-broken' property can be used to determine
if the firmware is buggy so that the underlying driver bug can be fixed
without breaking backwards compatibility.
Set the HCI_QUIRK_BDADDR_PROPERTY_BROKEN quirk for such platforms so
that the address is reversed when parsing the address property.

sock.h is pretty heavily used (5k objects rebuilt on x86 after

add a forward declaration of struct sk_filter instead.
This decreases the number of rebuilt objects when bpf.h
is touched from ~5k to ~1k.
There's a lot of missing includes this was masking. Primarily
in networking tho, this time.

The opcode of the command injected by commit 32646db8cc28 ("Bluetooth:
btqca: inject command complete event during fw download") uses the CPU
byte format, however it should always be little endian. In practice it
shouldn't really matter, since all we need is an opcode != 0, but still
let's do things correctly and keep sparse happy.

On WCN3990 downloading the NVM sometimes fails with a "TLV response
size mismatch" error:
[ 174.949955] Bluetooth: btqca.c:qca_download_firmware() hci0: QCA Downloading qca/crnv21.bin
[ 174.958718] Bluetooth: btqca.c:qca_tlv_send_segment() hci0: QCA TLV response size mismatch
It seems the controller needs a short time after downloading the
firmware before it is ready for the NVM. A delay as short as 1 ms
seems sufficient, make it 10 ms just in case. No event is received
during the delay, hence we don't just silently drop an extra event.

QCA BTSOC NVM is a customized firmware file and different vendors may
want to have different BTSOC configuration (e.g. Configure SCO over PCM
or I2S, Setting Tx power, etc.) via this file. This patch will allow
vendors to download different NVM firmware file by reading a device
property "firmware-name".

Latest qualcomm chips are not sending an command complete event for
every firmware packet sent to chip. They only respond with a vendor
specific event for the last firmware packet. This optimization will
decrease the BT ON time. Due to this we are seeing a timeout error
message logs on the console during firmware download. Now we are
injecting a command complete event once we receive an vendor specific
event for the last RAM firmware packet.

Redefinition of qca_uart_setup will help future Qualcomm Bluetooth
SoC, to use the same function instead of duplicating the function.
Added new arguments soc_type and soc_ver to the functions.
These arguments will help to decide type of firmware files
to be loaded into Bluetooth chip.
soc_type holds the Bluetooth chip connected to APPS processor.
soc_ver holds the Bluetooth chip version.

Some of the QCA BTSoC ROME functions, are used for different versions
or different make of BTSoC's. Instead of duplicating the same functions
for new chip, update names of the functions that are used for both
chips to keep this generic and would help in future when we would have
new BT SoC. To have generic text in logs updated from ROME to QCA where
ever possible. This avoids confusion to user, when using the future
Qualcomm Bluetooth SoC's. Updated BT_DBG, BT_ERR and BT_INFO with
bt_dev_dbg, bt_dev_err and bt_dev_info where ever applicable.
