The parameters (V4L2_META_FMT_IPU3_PARAMS) are bound to be different (for previous versions had a private IOCTL to pass them). There could be similarities between different versions of the IPUs but they're still not exactly the same. The hardware tends to change quite a bit between the generations. -- Regards, Sakari Ailus e-mail: sakari.ailus@xxxxxx XMPP: sailus@xxxxxxxxxxxxxx
