From 2d8bd2bf0d8eb752a58784ca890643176f595651 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.
