Hi,
this patch set adds the support for the Toshiba TC358746 Parallel
MIPI-CSI2 bridge device.
The last patch ("media: tc358746: update MAINTAINERS file") is optional,
due to Hans answer to Michael [1]. We can drop this patch if it isn't
needed.
I added the v4l2-compliance test in relation to [1], I used v4l2-compliance
version 1.16.0. Unfortunately the VIDIOC_(UN)SUBSCRIBE_EVENT/DQEVENT test
failed, but the device don't support events at all, as described in the
commit message of the 2nd patch.
The patche set was succefully rebased on top of media_tree/master and
compile tested.
