As I noted on patch 1, you need to send this to linux-mips + Ralf.

I forgot to CC Ralf on this version, but he took v9 (no change between v9 and v11) through linux-mips as can be seen here: http://patchwork.linux-mips.org/patch/11695/

This binding was updated, so you need:

				compatible = "fixed-partitions";

This has been fixed in mips-linux here: http://patchwork.linux-mips.org/patch/11914/

Thanks,
