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.
