[PATCH 1/4] ARM: sunxi: Restructure sunxi dts/dtsi files

[maxime.ripard@free-electrons.com (Maxime Ripard)]

Le 19/11/2012 12:09, Stefan Roese a ?crit :
> For the new sun4i/Cubieboard (A10) support, lets re-strucure the
> sun5i dts files to make it more generic. Those are the new
> dts/dtsi files:
> 
> sunxi.dtsi - Devices common to all Allwinner sunXi SoC's
> sun4i.dtsi - sun4i Devices, will include sunxi.dtsi
> sun5i.dtsi - sun5i Devices, will include sunxi.dtsi
> board.dts - will include either sun4i.dtsi or sun5i.dtsi
> 
> Additionally the "duart" label in the olinuxino.dts is changed to
> "uart1".
