Subject: [PATCH v6 0/4 RESEND] media: mgb4: YUV and variable framerate support

From: Martin Tůma <martin.tuma@...iteqautomotive.com>

Recent mgb4 FW update added support for the YUV image format and variable
framerates independent of the signal framerate. The following patches extend
the mgb4 driver with support for both features.

Changes in V6:
- Properly handle the timings when no signal is present.

Changes in V5:
- Removed surplus v4l2_format.type checks.
- Improved the patch descriptions.
- Splitted the frame rate limit patch into separate code/documentation parts.

Changes in V4:
- Splitted the output frame_rate handling fix from the variable frame rate
  addition patch.

Changes in V3:
- Use div_u64() for 64b division (fixes build error on ARM32)

Changes in V2:
- Added missing stride limit
