This patch defines common Armada 370 pinctrl settings for uart0 and uart1 interfaces:
uart0: MPP0-1 as default uart1: MPP41-42 as default Note: this patch has the potential to break out-of-tree users w/o specific pinctrl settings for their uart interfaces if the default above does not match their config.
