Subject: [PATCH] drm/i915: make A0 wa's applied to A1
Date: Mon, 26 Oct 2015 10:48:58 +0000	[thread overview]
Message-ID: <1445856538-5417-1-git-send-email-tim.gore@intel.com> (raw)

From: Tim Gore <tim.gore@intel.com>

Since A1 chips use the same GPU as A0, they need all the
same wa's in the i915 driver. Update some conditionals
to do this.
