RISC-V firmware drivers for v6.11
Microchip:
Support for writing "bitstream info" to the flash using the auto-update
driver. At this point the "bitstream info" is a glorified dtbo wrapper,
but there's plans to add more info there in the future. Additionally,
rework some allocations in the driver and use scope-based cleanup on
them.

Reset controller updates for v6.11
Move reset controller registration to the end in rzg2l-usbphy-ctrl, to
simplify the probe error path, add a new i.MX8MP AudioMix reset driver,
allow to build some drivers under COMPILE_TEST with fewer dependencies,
and use the devm_clk_get_enabled convenience wrapper in meson-audio-arb.
The latter causes a trivial merge conflict [1] with
b99e9c0961 ("reset: meson-audio-arb: Convert to platform remove callback returning void")
because I didn't manage to send that in last round. There is no overlap
though.

Arm FF-A driver updates for v6.11
The main addition is the split of bus and driver into distinct modules
The FF-A bus module is initialized at subsys_initcall level when builtin.
FF-A drivers initialization is now changed to module_init level so that
pKVM ffa proxy is all setup and running in case pKVM hypervisor needs to
trap and handle FF-A calls.
One of the reason for not having this split from the beginning is the
need to workaround the FF-A v1.0 NULL UUID. The FF-A bus layer called
into FF-A driver and populated the device UUID if it matches with the
driver attempting to match. Moving the workaround away from the FF-A
bus layer to the FF-A core driver as a bus notifier will help to remove
the dependency.

Arm SCMI driver updates for v6.11
The main addition this time is the support for platform to agent(p2a
also referred sometimes as notification or Rx) channel completion via
interrupt driven method. Currently, the OSPM agent clears or
acknowledge the receipt of the norification or delayed response by
updating the flags in the shared memory region which the platform is
expected to poll.
On some platforms that are completely interrupt driven, the OSPM
agent is expected to send a response message instead. This change
adds the support for the same.
Other changes include addition of a separate mailing list specific to
SCMI to allow open discussions about the interface itself in addition
to the kernel driver updates and support for system suspend via the
platform noification used on some systems.

"Lots of (mostly boring) fixes for syzbot bugs and rare(r) CI bugs.

One notable user reported bugfix, where we were forgetting to
correctly set the bucket data type, which should have been
BCH_DATA_need_gc_gens instead of BCH_DATA_free; this was causing us to
go emergency read-only on a filesystem that had seen heavy enough use
to see bucket gen wraparoud.
We're now starting to fix simple (safe) errors without requiring user
intervention - i.e. a small incremental step towards full self
healing.

A small prescaler is beneficial, as this improves the resolution of the
duty_cycle configuration. However if the prescaler is too small, the
maximal possible period becomes considerably smaller than the requested
value.
One situation where this goes wrong is the following: With a parent
clock rate of 208877930 Hz and max_arr = 0xffff = 65535, a request for
period = 941243 ns currently results in PSC = 1. The value for ARR is
then calculated to
ARR = 941243 * 208877930 / (1000000000 * 2) - 1 = 98301
This value is bigger than 65535 however and so doesn't fit into the
respective register field. In this particular case the PWM was
configured for a period of 313733.4806027616 ns (with ARR = 98301 &
0xffff). Even if ARR was configured to its maximal value, only period =
627495.6861167669 ns would be achievable.
Fix the calculation accordingly and adapt the comment to match the new
algorithm.
With the calculation fixed the above case results in PSC = 2 and so an
actual period of 941229.1667195285 ns.
