Subject: [PATCH 2/7] drm/i915: don't set transcoder bpc on CougarPoint
Date: Tue, 19 Apr 2011 12:12:36 -0700
Message-ID: <1303240361-6057-3-git-send-email-jbarnes@virtuousgeek.org> (raw)
In-Reply-To: <1303240361-6057-1-git-send-email-jbarnes@virtuousgeek.org>

BPC is specified in FDI RX on CPT and above, rather than in the transcoder.
