Subject: [PATCH] rcar-vin: Centralize black listing of pixel formats
Date: Fri, 5 Jul 2019 06:43:50 +0200 [thread overview]
Message-ID: <20190705044350.22766-1-niklas.soderlund+renesas@ragnatech.se> (raw)
Instead of scattering black listing of pixel formats who are not
supported on particular platforms move it to a central location.
