[PATCH RFC 07/46] imx-drm: Add mx6 hdmi transmitter support

From: Fabio Estevam fabio.estevam@freescale.com To: David Airlie airlied@linux.ie,Greg Kroah-Hartman gregkh@linuxfoundation.org,Sascha Hauer kernel@pengutronix.de,Shawn Guo shawn.guo@linaro.org

This is based on the initial work done by Sascha Hauer and Tony Prisk.

Tested on a mx6qsabresd.
