arm: mvebu: define and use common Armada 370 UART pinctrl settings (f8afeaea) · Commits · e / devices / android_kernel_fairphone_FP5

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.
