Subject: [PATCH 3/6] drm/i915/skl: Restrict the ring frequency table programming to SKL
Date: Mon, 29 Jun 2015 14:50:21 +0530	[thread overview]
Message-ID: <1435569624-28693-4-git-send-email-akash.goel@intel.com> (raw)
In-Reply-To: <1435569624-28693-1-git-send-email-akash.goel@intel.com>

From: Akash Goel <akash.goel@intel.com>

Ring frequency table programming is not required on BXT. Added separate
checks to enable the programming only for SKL & skip for BXT.

v2: Removed the BXT check from gen6_update_ring_freq function

Issue: VIZ-5144
Signed-off-by: Akash Goel <akash.goel@intel.com>
