From: Martin Tůma <[email protected]>
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 V2:
- Added missing stride limit

2.44.0
From: Martin Tůma <[email protected]>
Recent mgb4 firmwares have support for setting a variable framerate independent
of the signal framerate. Add/fix (the mgb4 driver already did promote
V4L2_CAP_TIMEPERFRAME, but it didn't work) support for V4L2_CAP_TIMEPERFRAME to
the driver to enable this feature.
