From d352f41e87e7226692d1346bb97c603615eeb817 Mon Sep 17 00:00:00 2001
From: Arnaud Ebalard <arno@natisbad.org>

Subject: arm: mvebu: define and use common Armada XP UART2/3 pinctrl settings
This patch defines common Armada XP pinctrl settings for uart2 and
uart3 interfaces (uart0 and uart1 rx/tx do not rely on MPP):
uart2: MPP42-43 as default
uart3: MPP44-45 as default
