T1040 has internal display interface unit (DIU) for driving video. T1040QDS supports video mode via -LCD using TI enconder -HDMI type interface via HDMI encoder Chrontel, CH7301C encoder which is I2C programmable is used as HDMI connector on T1040QDS. This patch add support to -enable Video interface for T1040QDS -route qixis multiplexing to enable DIU-HDMI interface on board -program DIU pixel clock gerenartor for T1040 -program HDMI encoder via I2C on board Signed-off-by: Priyanka Jain <Priyanka.Jain@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
