Silence the error on not finding registers in the of_clk_declare mod0 clk setup method, and also register mod0-clk support as a platform driver to work properly with mfd instantiated mod0 clocks.

Ok, I'll respin this patch adding such a comment. Regards, Hans -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
