The HW can capture both ODD and EVEN fields in separate buffers so it's
possible to support V4L2_FIELD_ALTERNATE. This patch add support for
this mode.
At probe time and when S_STD is called the driver will default to use
V4L2_FIELD_INTERLACED if the subdevice reports V4L2_FIELD_ALTERNATE. The
driver will only change the field type if the subdevice implements
G_STD, if not it will keep the default at V4L2_FIELD_ALTERNATE.
The user can always explicitly ask for V4L2_FIELD_ALTERNATE in S_FMT and
the driver will use that field format.

The media bus format reported by the adv7180 is wrong. Steve Longerbeam
posted a patch which changed the format to UYVY8_2X8 with the commit
message:
Change the media bus format from YUYV8_2X8 to UYVY8_2X8. Colors
now look correct when capturing with the i.mx6 backend. The other
option is to set the SWPC bit in register 0x27 to swap the Cr and Cb
output samples.
The rcar-vin driver was developed and tested with the adv7180 and
therefor suffers from the same issue, looking for the wrong media bus
format. The two errors corrected each other.
This patch takes Steve's patch and merge it with a fix for rcar-vin
driver. The rcar-vin driver is used used in together with the adv7180
och Koelsch and this ensures it will not break while fixing the adv7180
issue. I checked wit Steve and he was fine with me merging the patches.

Replace the current boolean parameter (full / !full) with an explicit

- VSP1_ENTITY_PARAMS_INIT for parameters to be configured at pipeline
initialization time only (V4L2 stream on or DRM atomic update)
- VSP1_ENTITY_PARAMS_RUNTIME for all parameters that can be freely
modified at runtime (through V4L2 controls)
This will allow future extensions when implementing image partitioning
support.

The frame-end function releases and completes the buffers on the input
and output entities of the pipe before marking the pipe->state as
'STOPPED'. This introduces a race whereby with the pipe->state still
'RUNNING', a QBUF handler can commence processing a frame before the
frame_end function has completed.
In the event that this happens, a frame queued by QBUF hangs due to the
incorrect pipe->state setting which prevents vsp1_pipeline_run from
issuing a CMD_STRCMD.
By locking the entire function we prevent this from occurring, but we
also change the locking state of the buffer release code. This has been
analysed visually as acceptable, but it must be considered that this now
causes the video->irqlock to be taken under the pipe->irqlock context.

Pipelines can only be run if all their video nodes are streaming. Commit
b4dfb9b35a ("[media] v4l: vsp1: Stop the pipeline upon the first
STREAMOFF") fixed the pipeline stop sequence, but introduced a race
condition that makes it possible to run a pipeline after stopping the
stream on a video node by queuing a buffer on the other side of the
pipeline.
Fix this by clearing the buffers ready flag when stopping the stream,
which will prevent the QBUF handler from running the pipeline.

This patch removes the soc_camera API dependency from pxa_camera.
In the current status :
- all previously captures are working the same on pxa270
- the s_crop() call was removed, judged not working
(see what happens soc_camera_s_crop() when get_crop() == NULL)
- if the pixel clock is provided by then sensor, ie. not MCLK, the dual
stage change is not handled yet.
=> there is no in-tree user of this, so I'll let it that way
- the MCLK is not yet finished, it's as in the legacy way,
ie. activated at video device opening and closed at video device
closing.
In a subsequence patch pxa_camera_mclk_ops should be used, and
platform data MCLK ignored. It will be the sensor's duty to request
the clock and enable it, which will end in pxa_camera_mclk_ops.

The driver should not ignore errors while registering the I2C
bus, as this device can't even minimally work without the buses,
as it uses those buses internally to talk with the several IP
blocks inside the chip.

The cx231xx_get_i2c_adap() function should return the I2C
adapter that will be used to talk with a device. It should never
be NULL, as otherwise the driver will try to dereference a
null pointer.
We might instead fix the callers, but if this condition
ever happens, it is really a driver bug, because i2c_port
should always be a value from enum CX231XX_I2C_MASTER_PORT.
Found when checking the code due to this bug:
[ 39.769021] BUG: unable to handle kernel NULL pointer dereference at 0000000000000002

The number of the cx231xx REQ for GPIO register set/get are wrong.
They should follow what's there at cx231xx-pcb-cfg.h.
Noticed while checking the cx231xx parser at the v4l-utils.

If something bad happens when switching between digital

This device uses GPIOs: 28 to switch between analog and
digital modes: on digital mode, it should be set to 1.
The code that sets it on analog mode is OK, but it misses
the logic that sets it on digital mode.

The cx231xx_set_agc_analog_digital_mux_select() callers
expect it to return 0 or an error. Returning a positive value
makes the first attempt to switch between analog/digital to fail.

With the current settings, only one channel locks properly.
That's likely because, when this driver was written, Brazil
were still using experimental transmissions.
Change it to reproduce the settings used by the newer drivers.
That makes it lock on other channels.
Tested with both PixelView SBTVD Hybrid (cx231xx-based) and
C3Tech Digital Duo HDTV/SDTV (em28xx-based) devices.

On this frontend, it takes a while to start output normal
TS data. That only happens on state S9. On S8, the TS output
is enabled, but it is not reliable enough.
However, the zigzag loop is too fast to let it sync.
As, on practical tests, the zigzag software loop doesn't
seem to be helping, but just slowing down the tuning, let's
switch to hardware algorithm, as the tuners used on such
devices are capable of work with frequency drifts without
any help from software.
