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 should be set to 0 and the bridge driver will fill in the right pad value internally depending on the current input or output and pass it along to the actual subdev driver.
