[PATCH] ARM: kirkwood: ReadyNAS Duo v2 .dts cleanup

[arno@natisbad.org (Arnaud Ebalard)]

The patch does some cleanup work on NETGEAR ReadyNAS Duo v2 .dts
file. Changes are listed below:

 - Converted GPIO voltage level from value to macros
 - Converted all numeric input key values to macros
 - Fixed bad spacing
 - Added some space between some nodes to improve readability
 - Made button node names more explicit
 - Added compatible string for PHY (marvell,mv88e1318s)
 - Added header for the file to describe content and author
 - Made G762 clock node name unique by including g762 in it
 - Fixed all node names and labels to use respectively '-' and '_'
 - Removed useless clocks and gpio-keys properties

Hi Jason,

This patch applies above the one adding gpio-poweroff driver for the Duo
v2 I just sent a few minutes ago. Most of the changes it contains were
Suggested-By: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> ;-)
If you have additional ideas or see things that should be fixed, I am
interested. As soon as I get a final version of this one, I will push
the same kind of cleanup patches for the RN102 and RN014 boards.
