[PATCH 0/4] Use DT to define more of the DNS320 & DNS325

[PATCH 0/4] Use DT to define more of the DNS320 & DNS325

[Jamie Lentin]

Thanks to sterling work by Andrew Lunn, more code has been turned into
devicetree bindings. The following takes what he's done, moves common
parts into a DT include file, adds LED and key bindings for both the 
DNS320 and DNS325. It has been tested on both devices.

This patchset replaces the DNS32? work in his patchset:-

git://github.com/lunn/linux.git v3.5-rc7-for-next-v3

I've not modified Andrew's DNS325 temperature sensor patch but 
included it in the patchset to make it more obvious I've tested it.

Thanks!

[PATCH 1/4] ARM: Kirkwood: Describe DNS325 temperature sensor in DT.

[Jamie Lentin]

From: Andrew Lunn <andrew@lunn.ch>

Now that we have I2C support in DT, describe the LM75 in
the DT file for the DNS325.
