From f8afeaea9611b5183b7919de4fb9333dedc72896 Mon Sep 17 00:00:00 2001 From: Arnaud Ebalard Date: Sat, 22 Nov 2014 00:46:18 +0100 Subject: [PATCH] arm: mvebu: define and use common Armada 370 UART pinctrl settings 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.
