Subject: [PATCH 1/7] drm/i915/skl+: Use proper bytes_per_pixel during WM calculation
Date: Thu, 14 Jan 2016 17:32:42 +0530	[thread overview]
Message-ID: <1452772968-24772-2-git-send-email-shobhit.kumar@intel.com> (raw)
In-Reply-To: <1452772968-24772-1-git-send-email-shobhit.kumar@intel.com>

From: "Kumar, Mahesh" <mahesh1.kumar@intel.com>

Don't always use bytes_per_pixel using y_plane=0, instead use it
according to pixel format. If NV12 use y_plane eqal to 1
