The Amlogic G12A SoC embeds a second CEC controller with a totally
different design.
The two controller can work in the same time since the CEC line can
be set to two different pins on the two controllers.
This second CEC controller is documented as "AO-CEC-B", thus the
registers will be named "CECB_" to differentiate with the other
AO-CEC driver.
Unlike the other AO-CEC controller, this one takes the Oscillator
clock as input and embeds a dual-divider to provide a precise
32768Hz clock for communication. This is handled by registering
a clock in the driver.
Unlike the other AO-CEC controller, this controller supports setting
up to 15 logical addresses and supports the signal_free_time settings
in the transmit function.
Unfortunately, this controller does not support "monitor" mode.

I previously added an RC_CORE dependency here, but missed the corner
case of CONFIG_VIDEO_SECO_CEC=y with CONFIG_RC_CORE=m, which still
causes a link error:
drivers/media/platform/seco-cec/seco-cec.o: In function `secocec_probe':
seco-cec.c:(.text+0x1b8): undefined reference to `devm_rc_allocate_device'
seco-cec.c:(.text+0x2e8): undefined reference to `devm_rc_register_device'
drivers/media/platform/seco-cec/seco-cec.o: In function `secocec_irq_handler':
seco-cec.c:(.text+0xa2c): undefined reference to `rc_keydown'
Refine the dependency to disallow building the RC subdriver in this case.
This is the same logic we apply in other drivers like it.

Media bus codes were being mapped to pixelformats, which causes a
limitation on vimc because not all pixelformats can be mapped to media
bus codes.
Also, media bus codes are an internal configuration from the device.
Userspace only assures media bus codes matches between pads and expects
the image in a given pixelformat. So we can allow almost any media bus
format to be configured between pads, except for debayer that expects a
media bus code of type bayer in the sink pad.

This change is a redesign in the formats and the way the ISC is
configured w.r.t. sensor format and the output format from the ISC.
I have changed the splitting between sensor output (which is also ISC input)
and ISC output.
The sensor format represents the way the sensor is configured, and what ISC
is receiving.
The format configuration represents the way ISC is interpreting the data and
formatting the output to the subsystem.
Now it's much easier to figure out what is the ISC configuration for input, and
what is the configuration for output.
The non-raw format can be obtained directly from sensor or it can be done
inside the ISC. The controller format list will include a configuration for
each format.
The old supported formats are still in place, if we want to dump the sensor
format directly to the output, the try format routine will detect and
configure the pipeline accordingly.
This also fixes the previous issues when the raw format was NULL which
resulted in many crashes for sensors which did not have the expected/tested
formats.

Commit 0650a91499e0 ("media: mtk-vcodec: Correct return type for mem2mem
buffer helpers") fixed the return types for mem2mem buffer helper
functions by changing a few local variables from vb2_buffer to
vb2_v4l2_buffer. However, it left a few accesses to vb2_buffer::planes
as-is, accidentally turning them into accesses to
vb2_v4l2_buffer::planes and resulting in values being read from/written
to the wrong place.
Fix this by inserting vb2_buf into these accesses so they mimic their
original behavior.

clang warns about a possible variable use that gcc never
complained about:
drivers/media/platform/davinci/isif.c:982:32: error: variable 'frame_size' is uninitialized when used here
[-Werror,-Wuninitialized]
dm365_vpss_set_pg_frame_size(frame_size);
^~~~~~~~~~
drivers/media/platform/davinci/isif.c:887:2: note: variable 'frame_size' is declared here
struct vpss_pg_frame_size frame_size;
^
1 error generated.
There is no initialization for this variable at all, and there
has never been one in the mainline kernel, so we really should
not put that stack data into an mmio register.
On the other hand, I suspect that gcc checks the condition
more closely and notices that the global
isif_cfg.bayer.config_params.test_pat_gen flag is initialized
to zero and never written to from any code path, so anything
depending on it can be eliminated.
To shut up the clang warning, just remove the dead code manually,
it has probably never been used because any attempt to do so
would have resulted in undefined behavior.

However, the structs trick gcc, making it to believe that
there's just one value for each.

The only way for p_set to be NULL would be if vin_coef_set would be an
