Since Jagan's V1 was out first, I will let Jagan pick whatever might be 
useful from the driver I posted, probably the O(1) clock rate 
calculation and some of the regmap stuff, and once there is some merged 
result, I am happy to test it on my hardware. The DSI83 is I think the 
same as DSI84, except with half of the channels.
