with a runtime check that the running hardware supports it.

If a process is interrupted while accessing the radio device and the

Allwinner H3 SoC contains deinterlace unit, which has several modes of
operation - bypass, weave, bob and mixed (advanced) mode. I don't know
how mixed mode works, but according to Allwinner it gives best results,
so they use it exclusively. Currently this mode is also hardcoded here.
For each interleaved frame queued, this driver produces 2 deinterlaced
frames. Deinterlaced frames are based on 2 consequtive output buffers,
except for the first 2, where same output buffer is given to peripheral
as current and previous.
There is no documentation for this core, so register layout and fixed
values were taken from BSP driver.
I'm not sure if maximum size of the image unit is capable to process is
governed by size of "flag" buffers, frequency or it really is some HW
limitation. Currently driver can process full HD image in ~15ms (7.5ms
for each capture buffer), which allows to process 1920x1080@60i video
smoothly in real time.

If VIDEO_OV5695 is y and V4L2_FWNODE is m, building fails:
drivers/media/i2c/ov5695.o: In function `ov5695_probe':
ov5695.c:(.text+0xf4c): undefined reference to `v4l2_async_register_subdev_sensor_common'
Select V4L2_FWNODE like OV5675 does.

According to the datasheet, both AD5821 and AD5820 share a compatible
register-set:

Some camera modules also refer that AD5823 is a replacement of AD5820:

Since kernel 4.16, i2c devices with DT compatible tag are modprobed
using their DT modalias.
Without this patch, if this driver is build as module it would never
be autoprobed.
There is no need to mask it with CONFIG_OF to allow ACPI loading, this
also builds find with CONFIG_OF=n.

This patch adds support for a programmable enable pin. It can be used in
situations where the ANA-vcc is not configurable (dummy-regulator), or
just to have a more fine control of the power saving.
The use of the enable pin is optional.

The sensor data sheet clearly state that 2592x1944 only works at 15 fps
make sure we don't try to miss configure the pll out of acceptable
range.
