powerpc/t1042RDB: Add Video - HDMI support
T1042 has internal display interface unit (DIU) for driving video.
T1042RDB 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 T1042RDB.
This patch add support to
-enable Video interface for T1042RDB
-route qixis multiplexing to enable DIU-HDMI interface on board
-program DIU pixel clock gerenartor for T1042
-program HDMI encoder via I2C on board
This patch refer to the upstream diu patch
(337b0c52b3296f371d04aef71a833e09110e0e6b) for T1040qds.
