Hi Ashwin,

Please consider including the original text in your replies.  It helps keep the

for the first time, they won't know the original question.

I recently did a diff of the stock 3.0.35 kernel and Freescale latest revision 
of their kernel, which is based on 3.0.35.  The diff was huge - around 47 MB, 
and the modifications to the source don't seem to be isolated to the typical 
directories.  They are all over the place.

I think that Freescale definitely went their own way when it comes to developing 
capture drivers.  As far as I can tell, they don't make use of soc camera or 
media controller (the linuxtv stuff).  You might want to start with one of the 
drivers in drivers/media/video/mxc/capture and see if you can use that as a 
basis for your mt9t112 driver.
