Pull tty/serial driver updates from Greg KH:
"Here is the big set of tty and serial driver changes for 6.6-rc1.
Lots of cleanups in here this cycle, and some driver updates. Short
summary is:
- Jiri's continued work to make the tty code and apis be a bit more
sane with regards to modern kernel coding style and types
- cpm_uart driver updates
- n_gsm updates and fixes
- meson driver updates
- sc16is7xx driver updates
- 8250 driver updates for different hardware types
- qcom-geni driver fixes
- tegra serial driver change
- stm32 driver updates
- synclink_gt driver cleanups
- tty structure size reduction
All of these have been in linux-next this week with no reported
issues. The last bit of cleanups from Jiri and the tty structure size
reduction came in last week, a bit late but as they were just style
changes and size reductions, I figured they should get into this merge
cycle so that others can work on top of them with no merge conflicts"

It is not allowed to call kfree_skb() from hardware interrupt
context or with hardware interrupts being disabled.
So replace kfree_skb() with dev_kfree_skb_irq() under
spin_lock_irqsave(). Compile tested only.

The quirks table was named "blacklist_table" which isn't a good
description for that table as devices detected using it weren't ignored
by the driver.
Rename the table to match what it actually does.

This introduces HCI_QUIRK_BROKEN_LE_CODED which is used to indicate
that LE Coded PHY shall not be used, it is then set for some Intel
models that claim to support it but when used causes many problems.

This improves the inband IR command handling for NXP BT chipsets.
When the IR vendor command is received, the driver injects a HW
error event, which causes a reset sequence in hci_error_reset().
The vendor IR command is sent to the controller while hci dev
is been closed, and FW is re-downloaded when nxp_setup() is
called during hci_dev_do_open().
The HCI_SETUP flag is set in nxp_hw_err() to make sure that
nxp_setup() is been called during hci_dev_do_open().
This also makes the nxp_setup() and power save functions more
generic.

This adds support for NXP IW624 chipset in btnxpuart driver
by adding FW name and bootloader signature. Based on the
loader version bits 7:6 of the bootloader signature, the
driver can choose between selecting secure and non-secure
FW files.
For cmd5 payload during FW download, this chip has addresses
of few registers offset by 1, so added boot_reg_offset to
handle the chip specific offset.

This removes the unnecessary check for CTS low after FW download.
After FW download is complete, the CTS line is already seen low.
It becomes high after 2 msec, and low again after FW initialization
is complete.
This makes the current check for CTS low redundant.
This removes the wait for CTS low section and increase delay to
1200msec instead, which is sufficiant for all NXP chipsets to
initialize FW.

This makes all those 'char's an explicit 'u8'. This is part of the
continuing unification of chars and flags to be consistent u8.
This approaches tty_port_default_receive_buf().
Note that we do not change signedness as we compile with
-funsigned-char.

The firmware for this chip has a slightly different naming scheme
compared to most others. For ROM Version 0x0200 we need to use

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

This patch adds code to check HCI_UART_PROTO_READY flag before
accessing hci_uart->proto. It fixes the race condition in
hci_uart_tty_ioctl() between HCIUARTSETPROTO and HCIUARTGETPROTO.
This issue bug found by Yu Hao and Weiteng Chen:
BUG: general protection fault in hci_uart_tty_ioctl [1]

This patch implement function .coredump() and dmp_hdr() in btusb
driver for MediaTek controller. FW core dump was triggered by FW
specific event to show something unexpected happened in the controller.
The driver would be responsible for collecting and uploading the device
core dump pieces in hci driver using core dump API. Once we finished
the whole process, the driver would reset the controller to recover the
kind of fatal error.

Since limited tracking device per condition, this feature is to support
tracking multiple devices concurrently.
When a pattern monitor detects the device, this feature issues an address
monitor for tracking that device. Let pattern monitor can keep monitor
new devices.
This feature adds an address filter when receiving a LE monitor device
event which monitor handle is for a pattern, and the controller started
monitoring the device. And this feature also has cancelled the monitor
advertisement from address filters when receiving a LE monitor device
event when the controller stopped monitoring the device specified by an
address and monitor handle.
Below is an example to know the feature adds the address filter.

This patch is added support Mediatek MT7925.
1. The firmware location of MT7925 will set to
/lib/firmware/mediatek/mt7925
2. Add Mediatek private data in hdev
to record the device for handle MT7925 flow.
3. Use the recoreded dev_id to condition chip reset flow.

New Intel platforms supports reset of Bluetooth device via ACPI DSM
methods. The legacy reset mechanism via GPIO will be deprecated in
future. This patch checks the platform support for reset methods and if
supported uses the same instead of legacy GPIO toggling method.
ACPI firmware supports two types of reset method based on NIC card.
(Discrete or Integrated).
1. VSEC Type - Vendor Specific Extended Capability. Here BT_EN and
BT_IF_SELECT lines are driven by a register in PCH cluster. This
interface is supported on discrete BT solution.
2. WDISABLE2 - In this soluton, W_DISABLE2 pin in M.2 is connected to
physical GPIO from PCH. The DSM interface shall toggle this to recover
from error.

Commit c13380a55522 ("Bluetooth: btusb: Do not require hardcoded
interface numbers") inadvertedly broke bluetooth on Intel Macbook 2014.
The intention was to keep behavior intact when BTUSB_IFNUM_2 is set and
otherwise allow any interface numbers. The problem is that the new logic
condition omits the case where bInterfaceNumber is 0.
Fix BTUSB_IFNUM_2 handling by allowing both interface number 0 and 2
when the flag is set.

For virtio-net we were getting CPU stall warnings, and fixed it by
calling the scheduler: see f8bb51043945 ("virtio_net: suppress cpu stall
when free_unused_bufs").
This driver is similar so theoretically the same logic applies.

A recent commit restored the original (and still documented) semantics
for the HCI_QUIRK_USE_BDADDR_PROPERTY quirk so that the device address
is considered invalid unless an address is provided by firmware.
This specifically means that this flag must only be set for devices with
invalid addresses, but the Broadcom driver has so far been setting this
flag unconditionally.
Fortunately the driver already checks for invalid addresses during setup
and sets the HCI_QUIRK_INVALID_BDADDR flag. Use this flag to indicate
when the address can be overridden by firmware (long term, this should
probably just always be allowed).

Since commit 3e4be65eb82c ("Bluetooth: hci_qca: Add poweroff support
during hci down for wcn3990"), the setup callback which registers the
debugfs interface can be called multiple times.
This specifically leads to the following error when powering on the
controller:
debugfs: Directory 'ibs' with parent 'hci0' already present!
Add a driver flag to avoid trying to register the debugfs interface more
than once.
