The imx8mq-mipi-csi2 MIPI CSI-2 receiver driver is used and maintained.
There is no reason to keep it in staging. The accompanying CSI bridge
driver that uses it is in drivers/media/platform/nxp as well.
One TODO is to get rid of csi_state's "state" and "lock" variables.
Especially make sure suspend/resume is working without them. That can
very well be worked on from the new location.
Also add a MAINTAINERS section for the imx8mq-mipi-csi2 mipi receiver
driver.

When capturing 1600x900, system could crash when system memory usage is
tight.
The way to reproduce this issue:
1. Use 1600x900 to display on host
2. Mount ISO through 'Virtual media' on OpenBMC's web
3. Run script as below on host to do sha continuously
#!/bin/bash
while [ [1] ];
do
find /media -type f -printf '"%h/%f"\n' | xargs sha256sum
done
4. Open KVM on OpenBMC's web
The size of macro block captured is 8x8. Therefore, we should make sure
the height of src-buf is 8 aligned to fix this issue.

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.

An ATR is a device that looks similar to an i2c-mux: it has an I2C
slave "upstream" port and N master "downstream" ports, and forwards
transactions from upstream to the appropriate downstream port. But it
is different in that the forwarded transaction has a different slave
address. The address used on the upstream bus is called the "alias"
and is (potentially) different from the physical slave address of the
downstream chip.
Add a helper file (just like i2c-mux.c for a mux or switch) to allow
implementing ATR features in a device driver. The helper takes care of
adapter creation/destruction and translates addresses at each transaction.
