* ARM: sunxi: Use the Synosys APB UART instead of ns8250Maxime Ripard2013-01-161-2/+4
| | | | | | | | | The UART controller used in the A10/A13 is the Synopsys DesignWare 8250. The wrong use of a regular 8250 driver may lead to a oops during kernel boot with "irq 17: nobody cared", because the apb UART as an extra interrupt that gets raised when writing to the LCR when busy.

* ARM: sunxi: Add sun4i and cubieboard supportStefan Roese2012-11-201-0/+9
| | | | | | | | | | This patch adds support for the Cubieboard based on the Allwinner A10/sun4i SoC. Currently only UART is supported. Other devices will eventually follow.

* ARM: sunxi: Restructure sunxi dts/dtsi filesStefan Roese2012-11-201-0/+66
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".
