Subject: [PATCH 1/5] drm/dp: Add DPCD OUI register defines
Date: Mon, 14 May 2012 16:05:45 -0400 [thread overview]
Message-ID: <1337025949-2355-2-git-send-email-ajax@redhat.com> (raw)
In-Reply-To: <1337025949-2355-1-git-send-email-ajax@redhat.com>
DisplayPort has an escape hatch by which sources and sinks can identify
each other. We would prefer not to notice this, but I suspect we're
going to need to.
