Re: MT9T111/MT9T112 aptina camera driver in linux-imx

Hi Ashwin,

Please consider including the original text in your replies.  It helps keep the 
conversation in context.  If someone else on the list is looking at this message 
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.
