From 622372309f292efe21dabaf46122a147864d239f Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 25 Jul 2015 16:23:23 +0900 Subject: [PATCH] ARM: dts: UniPhier: add UART and USB pinmux nodes The DT nodes in uniphier-pinctrl.dtsi provide the default pinctrl settings that would be suitable for most boards. You can still override them in your board DTS file if necessary.
