The SK Hynix Hi-846 is a 1/4" 8M Pixel CMOS Image Sensor. It supports
usual features like I2C control, CSI-2 for frame data, digital/analog
gain control or test patterns.

This driver supports the 640x480, 1280x720 and 1632x1224 resolution
modes. It supports runtime PM in order not to draw any unnecessary power.

The part is also called YACG4D0C9SHC and a datasheet can be found at
https://product.skhynix.com/products/cis/cis.go

The large sets of partly undocumented register values are for example
found when searching for the hi846_mipi_raw_Sensor.c Android driver.

The V4L2 async framework is generally used with the V4L2 fwnode, which
also depends on the former. There are a few exceptions but they are
relatively few.

At the same time there is a vast number of systems that need videodev
module, but have no use for v4l2-async that's now part of videodev.

In order to improve, split the v4l2-async into its own module. Selecting
V4L2_FWNODE also selects V4L2_ASYNC.

This also moves the initialisation of the debufs entries for async subdevs
to loading of the v4l2-async module. The directory is named as
"v4l2-async".

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.

in:

imx214 stands out as being the (only?) media I2C driver that still depends

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.

Instead of individually depending on MEDIA_CAMERA_SUPPORT (or forgetting
it), put all camera sensor, lens and flash drivers under
MEDIA_CAMERA_SUPPORT as a whole. The lens VCM devices didn't use to do
this, but make them depend on MEDIA_CAMERA_SUPPORT as well since there's
no use for these devices without that in practice.

If CONFIG_REGMAP_I2C is not set, building fails:

drivers/media/i2c/max2175.o: In function `max2175_probe':
max2175.c:(.text+0x1404): undefined reference to `__devm_regmap_init_i2c'

Select REGMAP_I2C to fix this.
