[PATCHv2,0/2] media: add support for the EDID EEODB

Message

Hans Verkuil Jan. 27, 2025, 11:03 a.m. UTC

Add support for the HDMI Forum EDID Extension Override Data Block
by introducing the v4l2_num_edid_blocks() helper function.

Update the adv7511-v4l2 driver to use this new function. This
fixes adv7511 support for EDIDs using the EEODB as otherwise only the
first two blocks would be read.

Regards,

	Hans

Changes since v1:

- add lots of comments to the v4l2_num_edid_blocks helper. There
  are a lot of constants there, so those needed proper comments.
