From 7d9bcebe13397f6621a44b998860ae0c8049b10c Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Mon, 25 Feb 2013 19:55:16 -0300 Subject: 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.
