Subject: [PATCH 02/11] drm/i915: Set scaler mode for NV12
Date: Thu, 30 Apr 2015 20:43:06 -0700	[thread overview]
Message-ID: <1430451795-9657-3-git-send-email-chandra.konduru@intel.com> (raw)
In-Reply-To: <1430451795-9657-1-git-send-email-chandra.konduru@intel.com>

This patch sets appropriate scaler mode for NV12 format.
In this mode, skylake scaler does either chroma-upsampling or
chroma-upsampling and resolution scaling.
