From 119f5173628aa7a0c3cf9db83460d40709e8241d Mon Sep 17 00:00:00 2001 From: CK Hu Date: Mon, 4 Jan 2016 18:36:34 +0100 Subject: drm/mediatek: Add DRM Driver for Mediatek SoC MT8173. This patch adds an initial DRM driver for the Mediatek MT8173 DISP subsystem. It currently supports two fixed output streams from the OVL0/OVL1 sources to the DSI0/DPI0 sinks, respectively.
