* ARM: sunxi: dt: Reorganize the dtsiMaxime Ripard2013-04-08
| | | | | | | | | In the early days, the A10 and A13 shared quite some code. Nowadays it shares less and less code, the A31 diverging even more, so it doesn't make much sense to continue to maintain this structure, just use one DTSI for every SoC, and that's it.

* arm: sunxi: use the right clock phandles for UARTsEmilio López2013-04-04
| | | | | | | | All the UARTs are connected to clock gates; now that our clock driver is able to handle them, make the switch. Signed-off-by: Emilio López <emilio@elopez.com.ar> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
* arm: sunxi: Add clock definitions for AXI, AHB, APB0, APB1 gatesEmilio López2013-04-04
| | | | | | | | This commit adds the corresponding DT bindings for all the AXI, AHB, APB0 and APB1 gates. Signed-off-by: Emilio López <emilio@elopez.com.ar> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
* ARM: sunxi: dt: Add uart3 dt nodeMaxime Ripard2013-03-29
| | | | | | | | Both A10 and A13 Allwinner SoCs have a Synopsys APB uart3 device available, so add it to the sunxi.dtsi file Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Acked-by: Emilio López <emilio@elopez.com.ar>
* ARM: sunxi: dt: Move uart0 to sun4i-a10.dtsiMaxime Ripard2013-03-29
| | | | | | | | | The UART0 is only available on the Allwinner A10 SoCs, and not on the A13, so move the uart0 node to sun4i-a10.dtsi. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Acked-by: Emilio López <emilio@elopez.com.ar> Tested-by: Emilio López <emilio@elopez.com.ar>
* ARM: sunxi: Rename uart nodes to serialMaxime Ripard2013-03-29
| | | | | | | The other architecture use serial@address for their uart nodes, so rename our uart dt nodes to be consistent Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
* ARM: sunxi: dt: Use clocks property instead of clock-frequency for the UARTsMaxime Ripard2013-03-29
| | | | | | | | | It will be especially useful when we will have the clock definitions in the device tree. Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com> Acked-by: Emilio López <emilio@elopez.com.ar> Tested-by: Emilio López <emilio@elopez.com.ar>
* arm: sunxi: rename clock compatible stringsEmilio López2013-03-27
| | | | | | | | | | | | | | | | | | | During the introduction of the Allwinner SoC platforms, sunxi was initially meant as a generic name for all the variants of the Allwinner SoC. It was ok at the time of the support of only the A10 and A13 that look pretty much the same; but it's beginning to be troublesome with the future addition of the Allwinner A31 (sun6i) that is quite different, and would introduce some weird logic, where sunxi would actually mean in some case sun4i and sun5i but without sun6i... Moreover, it makes the compatible strings naming scheme not consistent with other architectures, where usually for this kind of compability, we just use the oldest SoC name that has this IP, so let's do just this.

* arm: sunxi: Add clock definitions for the new clock driverEmilio López2013-03-23
| | | | | | | | | This introduces proper clock definitions on sunxi.dtsi, to be used with the new clock driver for sunxi. Signed-off-by: Emilio López <emilio@elopez.com.ar> Acked-by: Mike Turquette <mturquette@linaro.org> Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>
* ARM: sunxi: Use the Synosys APB UART instead of ns8250Maxime Ripard2013-01-16
| | | | | | | | | 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 Roese2012-11-20
| | | | | | | | | | 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 Roese2012-11-20
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".
