So this update is done to reflect the same. Also removed the code related to register address space iomap. Uses v4l2_i2c_new_subdev_board() instead of v4l2_i2c_new_probed_subdev() so that platform data can be added for subdevice configuration for polarities. This has incorporated comments against version v0 of the patch series. NOTE: This patch is dependent on the patch from Chaithrika for vpif display.
