Subject: [PATCH 13/15] OMAPDSS: HDMI5: add support to set infoframe & HDMI mode
Date: Tue, 24 Jun 2014 10:03:58 +0000	[thread overview]
Message-ID: <1403604240-16738-14-git-send-email-tomi.valkeinen@ti.com> (raw)
In-Reply-To: <1403604240-16738-1-git-send-email-tomi.valkeinen@ti.com>

Instead of using hardcoded AVI infoframe, and a custom HDMI/DVI mode
selection based in internal videomode tables, add support to set the
infoframe and HDMI/DVI mode.
