[GIT PULL v2 FOR v5.5] ti-vpe maintenance, add V4L2_CTRL_TYPE_AREA/V4L2_CID_UNIT_CELL_SIZE

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This PR adds support for V4L2_CID_UNIT_CELL_SIZE and the V4L2_CTRL_TYPE_AREA
control type. It also adds support for providing a default value for compound
controls (will be useful for stateless codec support as well).

It also adds a maintenance series for ti-vpe. Note the addition of a pixel
encoding enum for v4l2_format_info.

Changes since the previous PR:

- Fixed up some mismatched email addresses
- Fixed up some incorrect commit IDs in 'Fixes:' lines

Regards,

	Hans
