From 51c1327876f35d61c8bdd81fc96e1b501c9380ee Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 26 Apr 2012 13:53:59 +0200 Subject: drm: Renesas SH Mobile DRM driver The SH Mobile LCD controller (LCDC) DRM driver supports the main graphics plane in RGB and YUV formats, as well as the overlay planes (in alpha-blending mode only). Only flat panel outputs using the parallel interface are supported. Support for SYS panels, HDMI and DSI is currently not implemented.
