[PATCH 07/17] drm: rcar-du: Add R8A77965 support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The R8A77965 (M3-N) SoC provides VGA, HDMI and LVDS output.

This platform is unusual in that the VGA is connected to DU3 leaving DU2
unpopulated. This is reflected by the channel_mask accordingly.
