Some SoC(e.g NXP imx8MQ) may have a wrong default power down scale
setting so need init it to be the correct value, the power down
scale setting description in DWC3 databook:
Power Down Scale (PwrDnScale)
The USB3 suspend_clk input replaces pipe3_rx_pclk as a clock source to
a small part of the USB3 core that operates when the SS PHY is in its
lowest power (P3) state, and therefore does not provide a clock.
The Power Down Scale field specifies how many suspend_clk periods fit
into a 16 kHz clock period. When performing the division, round up the
remainder.
For example, when using an 8-bit/16-bit/32-bit PHY and 25-MHz Suspend
clock,
Power Down Scale = 25000 kHz/16 kHz = 13'd1563 (rounder up)
So use the suspend clock rate to calculate it.

During a reply, the target gets woken up and then the priority of the
replier is restored. The order is such to allow the target to process
the reply ASAP. Otherwise, we risk the sender getting scheduled out
before the wakeup happens. This strategy reduces transaction latency.
However, a subsequent transaction from the same target could be started
before the priority of the replier gets restored. At this point we save
the wrong priority and it gets reinstated at the end of the transaction.
This patch allows the incoming transaction to detect the race condition
and save the correct next priority. Additionally, the replier will abort
its pending priority restore which allows the new transaction to always
run at the desired priority.

Add vendor hook for passing events to client drivers.
We have some limitation to achieve the goal of input performance
without modification of kernel. So I would like you to add vendor
hook and please review the reason why I want to add it.
As the users trigger input actions, we need to support the input
operation and the what the users want to do so that there's no delay.
So we've developed and used "input booster" controling some resources
properly during input operations according to input type.
Android already has the booster in framework to support input actions
however this way has a long latency to control resources.
To reduce latency, we've placed the booster in kernel side for high
responsiveness and it guarantees faster than framework booster.
In addtion, I applied Samsung's own concept to the booster.
And it has been operated stably on all Galaxy models for about 10 years.
So we need
- add function to notify input events delivered to client in evdev.

When handling host stage-2 faults the hypervisor currently updates the
CPU _and_ IOMMUs page-tables. However, since we currently proactively
map accessible PA ranges into IOMMUs, updating them during stage-2
faults is unnecessary -- it only needs to be done during ownership
transitions. Optimize this by skipping the IOMMU updates from the host
memory abort path, which also reduces contention on the host stage-2
lock during boot and saves up to 1.1 sec of boot time on Pixel 6.

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.

This patch aims to add UVC_GUID_FORMAT_H265
High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2.
They describe the same video encoding method.
So for handling their behavior is the same.
However, when external camera device describes this encoding method,
some use hevc, some use h265.
There is no uniform specification to describe this encoding method.
So if an external camera device use h265 to describe this encoding method,
driver will not recognize it.
Therefore, this patch is to enable driver to read HEVC/H265
and convert it to V4L2_PIX_FMT_HEVC.

If add_memory_subsection() is called with a size of
memory_block_size_bytes, it calls into add_memory(), which declares
the region as system ram, and adds it to the buddy allocator. This
is inconsistent with the behavior of add_memory_subsection() for
other sizes, for which it does not add the memory to buddy and
instead reserves it for the caller's private use.
