From 084701ae2c83d8b66ec732f555fa0630649d6be2 Mon Sep 17 00:00:00 2001 From: Shashank Sharma Date: Fri, 21 Jul 2017 20:55:08 +0530 Subject: [PATCH] drm/i915: set colorspace for YCBCR420 outputs When output colorspace is YCBCR420, we have to load the corresponding colorspace in AVI infoframe. This patch fills the colorspace of AVI infoframe as per the output mode.
