RE: [PATCH] soc-camera: Add mt9t112 camera support

Guennadi,

I am not sure what you mean by ATM sensor. Is it not a
Aptina/Micron sensor giving Raw Bayer RGB or Yuv data?
Not sure what prevents it from interfacing with VPFE.
In otherwords, how is this different from mt9t031/mt9t001
in terms of hardware signals available to interface to
a SOC?
