[PATCH v2] media: v4l2-common: add Y12 to v4l2_format_info()

Posted by Tomi Valkeinen 2 weeks, 4 days ago

Add the V4L2_PIX_FMT_Y12 (12-bit greyscale stored in 16 bit container)
to the v4l2_format_info table.

Changes in v2:
- Drop V4L2_PIX_FMT_YUV24 which was already added upstream
- Link to v1: https://patch.msgid.link/20260806-v4l2-format-info-y12-yuv24-v1-1-de2dc061be02@ideasonboard.com
