[PATCH 10/15] ARM: dts: kirkwood: set default pinctrl for SPI0
From: Sebastian Hesselbarth
Date: Wed Apr 30 2014 - 08:57:29 EST
Most Kirkwood boards use the default SPI0 pinctrl setting anyway. Add a
default pinctrl setting to the toplevel SoC SPI0 node and put a note
in front of the corresponding pinctrl node to overwrite the setting
on board level.
Currently, only T5325 is using a different setting and already
overwrites the corresponding pinctrl node.
