[PATCH v2 2/3] ARM: dts: orion5x: split linkstation lswtgl into common and device parts
Roger Shimizu

Fri Feb 5 21:59:52 PST 2016
In order to support more linkstation devices, common part of current
.dts file goes into .dtsi file. Some .dtsi start with "mvebu-" prefix
because other kirkwood based linkstation devices are similar, and
will be migrated to use these .dtsi some time later.
- orion5x-linkstation.dtsi
- mvebu-linkstation-fan.dtsi
- mvebu-linkstation-gpio-simple.dtsi
while all rest part remains in device specific .dts file:
- orion5x-linkstation-lswtgl.dts
