Subject: [PATCH 10/10] drm/i915: Fixup non-24bpp support for VGA screens on Haswell
Date: Fri, 22 Feb 2013 01:05:13 +0100	[thread overview]
Message-ID: <1361491513-14231-19-git-send-email-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <1361491513-14231-1-git-send-email-daniel.vetter@ffwll.ch>

The LPT PCH only supports 8bpc, so we need to force the pipe bpp
to the right value.
