Subject: [PATCH 13/15] fbdev: sh_mobile_hdmi: improve HDMI PHY parameters
Date: Fri, 03 Sep 2010 07:20:35 +0000 [thread overview]
Message-ID: <Pine.LNX.4.64.1009030916300.2883@axis700.grange> (raw)
High monitor resolutions also require higher clock frequencies, current HDMI
PHY parameters do not work well for resolutions higher than 720p.
