[media] v4l: omap4iss: ipipeif: Shift input data according to the input format
Input samples must be left-aligned on the ISIF 16-bit data bus. Configure the 16-to-16-bit selector to shift data according to the input format. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
