66f92c4e17 media: coda: add RC enable controls
Currently the encoder enables the rate control algorithms if the bitrate
control is non-zero. Implement the V4L2_CID_MPEG_VIDEO_FRAME_RC_ENABLE
and V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE controls to allow userspace to
choose frame-level or macroblock-level rate control updates, or to
explicitly disable rate control. Both controls are initially enabled to
keep the current behavior.

don't call 'v4l2_async_notifier_parse_fwnode_endpoints_by_port'

'v4l2_fwnode_endpoint_parse' to parse the remote endpoints
and then register each async subdev with

since that is a driver error. But they still continue, potentially

The boards listed below use i2c device drivers and have
tuner_type equal TUNER_ABSENT. This means additional support
is required to enable the analog tuning capability, a case
statement is used to identify these models.

Models with analog tuning enabled:
- CX231XX_BOARD_HAUPPAUGE_930C_HD_1114xx (tested)
- CX231XX_BOARD_HAUPPAUGE_935C (tested)
- CX231XX_BOARD_HAUPPAUGE_955Q (tested)
- CX231XX_BOARD_HAUPPAUGE_975 (tested)
- CX231XX_BOARD_EVROMEDIA_FULL_HYBRID_FULLHD (untested)

The EvroMedia model was added, since it uses the si2157
tuner and the board profile claims it has analog inputs.

dd844fb8e5 media: platform: fcp: Set appropriate DMA parameters
Enabling CONFIG_DMA_API_DEBUG=y and CONFIG_DMA_API_DEBUG_SG=y will
enable extra validation on DMA operations ensuring that the size
restraints are met.

When using the FCP in conjunction with the VSP1/DU, and display frames,
the size of the DMA operations is larger than the default maximum
segment size reported by the DMA core (64K). With the DMA debug enabled,
this produces a warning such as the following:

"DMA-API: rcar-fcp fea27000.fcp: mapping sg segment longer than device
claims to support [len=3145728] [max=65536]"

We have no specific limitation on the segment size which isn't already
handled by the VSP1/DU which actually handles the DMA allcoations and
buffer management, so define a maximum segment size of up to 4GB (a 32
bit mask).

9429e7072f media: imx.rst: Fix the MIPI CSI-2 virtual channel
The current instructions for imx6q-sabresd do not lead to functional
capture on OV5640 MIPI CSI-2.

The reason for this, as explained by Steve Longerbeam, is that OV5640 by
default transmits on virtual channel 0, not channel 1 as is given in the
instructions.

Adapt the instructions to use virtual channel 0 so that a working
camera setup can be achieved on imx6q-sabresd.

Also, since we are using an IC direct conversion pipeline, improve
the example by demonstrating colorspace and scaling.

33d236371f media: imx-media-csc-scaler: Use a shorter name for driver
Currently v4l2-compliance tool returns the following output:

Compliance test for imx-media-csc-s device /dev/video8:

Driver Info:
        Driver name      : imx-media-csc-s
        Card type        : imx-media-csc-scaler
        Bus info         : platform:imx-media-csc-scaler

The driver name string is limited to 16 characters, so provide
a shorter name in order to get a better output.

While at it, use the same shorter name for driver, card and platform.

Rename the format lookup and enumeration functions according to their
usage:

- Rename imx_media_(find|enum)_format() to *_pixel_format() to
  explicitly state on what formats the functions operate. This aligns
  the naming scheme with the media bus and IPU format functions that
  already end with *_mbus_format() and *_ipu_formats().

- Rename all enumeration functions to pluralize 'formats' at the end, as
  they enumerate multiple formats.
