The RDACM21 is a GMSL camera supporting 1280x1080 resolution images
developed by IMI based on an Omnivision OV10640 sensor, an Omnivision
OV490 ISP and a Maxim MAX9271 GMSL serializer.

The driver uses the max9271 library module, to maximize code reuse with
other camera module drivers using the same serializer, such as rdacm20.

The OV8865 is a 8 Mpx CMOS image sensor producing 3264x2448 at 30 fps.
Other modes (including some with sub-sampling) are available too.
It outputs 10-bit bayer CFA data through a MIPI CSI-2 interface with
up to 4 lanes supported.

Some register initialisation sequences are still needed for this driver,
as they cover registers for which no documentation is available.

This work is based on the first version of the driver submitted by
Kévin L'hôpital, which was adapted to mainline from the Allwinner BSP.
This version is a rewrite of the first version that matches the structure
of the OV5648 driver, with explicit PLL configuration, all the necessary
mode-specific fields, associatied registers and reduced static sequences.

It was tested with the Banana Pi Camera Board v3 and the Banana Pi M3.

After the recent conversion of the media build infrastructure to select
V4L2 components instead of depending on their presence, which took place
in:
32a363d0 ("media: Kconfig files: use select for V4L2 subdevs and MC")

imx214 stands out as being the (only?) media I2C driver that still depends
on a V4L2 core symbol instead of selecting it.

This confuses the build system which claims it has detected a circular
dependency when other drivers select the same symbol as the imx214
driver does.

On some board it is possible that the sensor 'powerdown' and or 'reset'
pin might be controlled by gpio instead of being tied.

To implement we add pm_runtime support which will handle the power
up/down sequence when it is available otherwise the sensor will be
powered on at module insertion/probe and powered off at module removal.

Now originally the driver assumed that the sensor would always stay
powered and keep its register setting. We cannot assume this anymore, so
every time we "power up" we need to re-program the initial registers
configuration first. This was previously done only at probe time.
