The previous API and negotiation of mbus codes and pixel formats was broken, and has been completely redone. The negotiation of media bus codes should be as follows: CSI: sink pad direct src pad IDMAC src pad -------- ---------------- ------------- RGB (any) IPU RGB RGB (any) YUV (any) IPU YUV YUV (any) Bayer N/A must be same bayer code as sink
The IDMAC src pad should also use the internal 32-bit RGB / YUV format, except if bayer/raw mode is selected, in which case the attached capture video device should only allow a single mode corresponding to the output pad media bus format. regards Philipp -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
