7bba9e81a6 extcon: Use unique number for the extcon device ID
The use of atomic variable is still racy when we do not control which
device has been unregistered and there is a (theoretical) possibility
of the overflow that may cause a duplicate extcon device ID number
to be allocated next time a device is registered.

Replace above mentioned approach by using IDA framework.

566825a31f extcon: Remove dup device name in the message and unneeded error check
The device name is already printed with dev_err(), no need to repeat.
The device pointer itself is not supposed to be an error point, drop
that check.

The connector child node of the TUSB320 device might be linked with a
dual-role capable USB controller. Add driver support for detecting a
usb_role_switch and setting its state in the typec interrupt handler.
This follows similar practice in other drivers in the typec subsystem,
which this extcon driver can opt-in to.

18eb81d804 extcon: usbc-tusb320: add accessory detection support
The TUSB320 can detect the following types of accessory:

  - Audio Accessory
  - Audio Accessory with charge-thru
  - Debug Accessory (DFP)
  - Debug Accessory (UFP)

Moreover, the typec subsystem can be informed of this through the
typec_set_mode() function. The information will be propagated to any
linked typec muxes. Add the necessary support to the driver.

Note that for the Debug Accessory modes, an educated guess was made that
for the USB data role, DFP implies HOST and UFP implies DEVICE. But this
might want to be made configurable at a later date.

fe551bc9dc extcon: qcom-spmi: Switch to platform_get_irq_byname_optional
Valid configurations for the extcon interrupt declarations are

- usb_id
- usb_vbus
- (usb_id | usb_vbus)

In the case of a standalone usb_id or usb_vbus failure to find one of the
interrupts shouldn't generate a warning message. A warning is already in
place if both IRQs are missing.

Switch to using platform_get_irq_byname_optional() in order to facilitate
this behaviour.

347774f7fc dt-bindings: pm8941-misc: Fix usb_id and usb_vbus definitions
dts validation is throwing an error for me on 8916 and 8939 with
extcon@1300. In that case we have usb_vbus but not usb_id.

It wasn't immediately obvious if there was a valid use-case for the
existing code for usb_id in isolation, however discussing further, we
concluded that usb_id, usb_vbus or (usb_id | usb_vbus) are valid
combinations as an external IC may be responsible for usb_id or usb_vbus.

Expand the definition with anyOf to capture the three different valid
modes.

3adbaa30d9 extcon: usbc-tusb320: Unregister typec port on driver removal
The driver can register a typec port if suitable firmware properties are
present. But if the driver is removed through sysfs unbind, rmmod or
similar, then it does not clean up after itself and the typec port
device remains registered. This can be seen in sysfs, where stale typec
ports get left over in /sys/class/typec.

In order to fix this we have to add an i2c_driver remove function and
call typec_unregister_port(), which is a no-op in the case where no
typec port is created and the pointer remains NULL.

In the process we should also put the fwnode_handle when the typec port
isn't registered anymore, including if an error occurs during probe. The
typec subsystem does not increase or decrease the reference counter for
us, so we track it in the driver's private data.

Note that the conditional check on TYPEC_PWR_MODE_PD was removed in the
probe path because a call to tusb320_set_adv_pwr_mode() will perform an
even more robust validation immediately after, hence there is no
functional change here.

 "Two fixes for debugobjects:

   - Prevent the allocation path from waking up kswapd.

     That's a long standing issue due to the GFP_ATOMIC allocation flag.
     As debug objects can be invoked from pretty much any context waking
     kswapd can end up in arbitrary lock chains versus the waitqueue
     lock

   - Correct the explicit lockdep wait-type violation in
     debug_object_fill_pool()"

9bd5386c65 A set of fixes for interrupt chip drivers:
- Prevent loss of state in the MIPS GIC interrupt controller.
 
   - Disable pseudo NMIs on Mediatek based Chromebooks as they have
     firmware issues which cause instantenous chrashes and freezes
     wen pseudo NMIs are used.
 
   - Fix the error handling path in the MBIGEN driver and a defined but not
     used warning in the meson-gpio interrupt chip driver.

18713e8a68 ARM: SoC fixes for 6.4
There have not been a lot of fixes for for the soc tree in 6.4, but
 these have been sitting here for too long.
 
 For the devicetree side, there is one minor warning fix for vexpress,
 the rest all all for the the NXP i.MX platforms: SoC specific bugfixes
 for the iMX8 clocks and its USB-3.0 gadget device, as well as board
 specific fixes for regulators and the phy on some of the i.MX boards.
 
 The microchip risc-v and arm32 maintainers now also add a shared
 maintainer file entry for the arm64 parts.
 
 The remaining fixes are all for firmware drivers, addressing mistakes in
 the optee, scmi and ff-a firmware driver implementation, mostly in the
 error handling code, incorrect use of the alloc_workqueue() interface in
 SCMI, and compatibility with corner cases of the firmware implementation.

793a539ac7 cxl: Explicitly initialize resources when media is not ready
When media is not ready do not assume that the capacity information from
the identify command is valid, i.e. ->total_bytes
->partition_align_bytes ->{volatile,persistent}_only_bytes. Explicitly
zero out the capacity resources and exit early.

Given zero-init of those fields this patch is functionally equivalent to
the prior state, but it improves readability and robustness going
forward.

47ee3f1dd9 x86: re-introduce support for ERMS copies for user space accesses
I tried to streamline our user memory copy code fairly aggressively in
commit adfcf4231b ("x86: don't use REP_GOOD or ERMS for user memory
copies"), in order to then be able to clean up the code and inline the
modern FSRM case in commit 577e6a7fd5 ("x86: inline the 'rep movs' in
user copies for the FSRM case").

We had reports [1] of that causing regressions earlier with blogbench,
but that turned out to be a horrible benchmark for that case, and not a
sufficient reason for re-instating "rep movsb" on older machines.

However, now Eric Dumazet reported [2] a regression in performance that
seems to be a rather more real benchmark, where due to the removal of
"rep movs" a TCP stream over a 100Gbps network no longer reaches line
speed.

And it turns out that with the simplified the calling convention for the
non-FSRM case in commit 427fda2c8a ("x86: improve on the non-rep
'copy_user' function"), re-introducing the ERMS case is actually fairly
simple.

Of course, that "fairly simple" is glossing over several missteps due to
having to fight our assembler alternative code.  This code really wanted
to rewrite a conditional branch to have two different targets, but that
made objtool sufficiently unhappy that this instead just ended up doing
a choice between "jump to the unrolled loop, or use 'rep movsb'
directly".

Let's see if somebody finds a case where the kernel memory copies also
care (see commit 68674f94ff: "x86: don't use REP_GOOD or ERMS for
small memory copies").  But Eric does argue that the user copies are
special because networking tries to copy up to 32KB at a time, if
order-3 pages allocations are possible.

In-kernel memory copies are typically small, unless they are the special
"copy pages at a time" kind that still use "rep movs".

abf5422e82 Arm FF-A fixes for v6.4
Quite a few fixes to address set of assorted issues:
 1. NULL pointer dereference if the ffa driver doesn't provide remove()
    callback as it is currently executed unconditionally
 2. FF-A core probe failure on systems with v1.0 firmware as the new
    partition info get count flag is used unconditionally
 3. Failure to register more than one logical partition or service within
    the same physical partition as the device name contains only VM ID
    which will be same for all but each will have unique UUID.
 4. Rejection of certain memory interface transmissions by the receivers
    (secure partitions) as few MBZ fields are non-zero due to lack of
    explicit re-initialization of those fields
