The PrP can resize every format which is supported as input by the eMMa. Currently, the driver supports 2 input formats: RGB565 and YUV422 (YUYV) (see mx27_emma_prp_table[]). Since the commit of resizing registers is done in the stream_start callback this makes sure that resizing won't be applied to unknown formats. Regards. -- Javier Martin Vista Silicon S.L.
