Hi Murali. Thanks for the patch.

There is now a common binding for the number of chip select lines. Otherwise the patch and the binding look fine to me. g. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
