Currently the VIDIOC_SUBDEV_G/S_EDID and struct v4l2_subdev_edid are subdev APIs. However, that's in reality quite annoying since for simple video pipelines there is no need to create v4l-subdev device nodes for anything else except for setting or getting EDIDs. What happens in practice is that v4l2 bridge drivers add explicit support for VIDIOC_SUBDEV_G/S_EDID themselves, just to avoid having to create subdev device nodes just for this. So this patch series makes the ioctls available as regular ioctls as well. In that case the pad field is interpreted as the input or output index as returned by ENUMINPUT/OUTPUT. Rebased to the latest master branch, but otherwise unchanged from the REVIEWv1 patch series: http://www.spinics.net/lists/linux-media/msg74022.html Regards, Hans The following changes since commit f2d7313534072a5fe192e7cf46204b413acef479: [media] drx-d: add missing braces in drxd_hard.c:DRXD_init (2014-03-09 09:20:50 -0300) are available in the git repository at: git://linuxtv.org/hverkuil/media_tree.git edid for you to fetch changes up to 66090d7c5b127fa4a461394261c50ca2364a286a: DocBook v4l2: update the G/S_EDID documentation (2014-03-10 13:36:29 +0100) ---------------------------------------------------------------- Hans Verkuil (5): v4l2-compat-ioctl32: fix wrong VIDIOC_SUBDEV_G/S_EDID32 support. v4l2: allow v4l2_subdev_edid to be used with video nodes v4l2: add VIDIOC_G/S_EDID support to the v4l2 core. adv*: replace the deprecated v4l2_subdev_edid by v4l2_edid.
