ITU-R BT.656 only specifies 8-bit (or 10-bit) streams, the 16-bit BT.656 SDR/DDR modes with two values on the bus at the same time are somewhat nonstandard. As far as I can tell, this mode should correspond to the CSI's BT.1120 SDR mode (Figure 37-20 in MX6DQ Reference Manual v1), so I'd expect CSI_SENS_CONF to be configured as DATA_WIDTH=1 (8-bit components), SENS_DATA_FORMAT=1 (YUV422), SENS_PRCTL=5 (progressive BT.1120 SDR). regards Philipp -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
