  This reverts commit d509835e32bd761a2b7b446034a273da568e5573. That commit
breaks support for the generic pass-through mode in the driver for formats,
not natively supported by it. Besides due to a merge conflict it also breaks
driver compilation:

drivers/media/video/mx2_camera.c: In function 'mx2_camera_set_bus_param':
drivers/media/video/mx2_camera.c:937: error: 'pixfmt' undeclared (first use in this function)
drivers/media/video/mx2_camera.c:937: error: (Each undeclared identifier is reported only once
drivers/media/video/mx2_camera.c:937: error: for each function it appears in.)

Can this be applied?

It is breaking mxs_defconfig for one month now.

Thanks,
