The original docs have "this can only cause a STOP to be generated if a GMBUS cycle is generated, the GMBUS is currently in a data phase, or it is in a WAIT phase." So from that it seems STOP | INDEX? | WAIT is always a valid combination and is explicitly listed in the register set. I defer to actual testing though ;) -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/dri-devel
