From: Rodrigo Vivi Date: Mon, 25 Feb 2013 22:55:16 +0000 (-0300) Subject: drm/i915: Use cpu_transcoder for HSW_TVIDEO_DIP_* instead of pipe X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7d9bcebe13397f6621a44b998860ae0c8049b10c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Use cpu_transcoder for HSW_TVIDEO_DIP_* instead of pipe While old platforms had 3 transcoders and 3 pipes (1:1), HSW has 4 transcoders and 3 pipes. These regs were being used only by HDMI code where pipe is always the same thing as cpu_transcoder. This patch allow us to use them for DP, specially for TRANSCODER_EDP. v2: Adding HSW_TVIDEO_DIP_VSC_DATA to transmit vsc to eDP.
