Hi Mani,

Thank you for the patches.

I've just been made aware of your work. I also worked on an IMX296
sensor driver in parallel, which I will post to the list. My driver
doesn't hardcode the resolution but computes register values at runtime,
so I wonder if it could be a better option. I'll post it now.
