The MT9M032 is a parallel 1.6MP sensor from Micron controlled through I2C.
The driver creates a V4L2 subdevice. It currently supports cropping, gain,
exposure and v/h flipping controls in monochrome mode with an
external pixel clock.

Changes in V4
* Use register(-value) constants from MT9P031 to fill in gaps
* Use MT9M032_CHIP_VERSION_VALUE instead of magical number
* Use i2c_smbus_{read,write}_word_swapped
* Minor error return code handling fixes
Changes in V3
* rebased to current mainline
* removed unneeded includes
* remove all translation code to hide black or active boundry sensor pixels.
Userspace now needs to select
crop in original device coordinates.
* remove useless consts, casts and defines
* changed enum_frame_size to return min == max
* removed duplicated input validation
* validate crop rectangle on set_crop
Changes in V2
* ported to current mainline
* Moved dispatching for subdev ioctls VIDIOC_DBG_G_REGISTER and
VIDIOC_DBG_S_REGISTER into v4l2-subdev
* Removed VIDIOC_DBG_G_CHIP_IDENT support
* moved header to media/
* Fixed missing error handling
* lowercase hex constants
* moved v4l2_get_subdevdata to register access helpers
* use div_u64 instead of do_div
* moved all know register values into #define:ed constants
* Fixed error reporting, used clamp instead of open coding.
* lots of style fixes.
* add try_ctrl to make sure user space sees rounded values
* Fixed some problem in control framework usage.
* Fixed set_format to force width and height setup via crop. Simplyfied code.
