Subject: [media] v4l: vsp1: Disable VYUY on Gen3
Author: Laurent Pinchart <laurent.pinchart+rene...@ideasonboard.com>
Date: Thu Sep 15 16:08:09 2016 -0300
The VYUY format isn't supported on Gen3 hardware, disable it.
Gen2 hardware supports VYUY in practice even though the documentation
doesn't advertise it, so keep it for Gen2 devices.
