+Binding for Freescale QorIQ AHCI SATA Controller
+
+Required properties:
+ - reg: Physical base address and size of the controller's register area.
+ - compatible: Compatibility string. Must be 'fsl,<chip>-ahci', where
+ chip could be ls1021a, ls2085a, ls1043a etc.
+ - clocks: Input clock specifier. Refer to common clock bindings.
+ - interrupts: Interrupt specifier. Refer to interrupt binding.
+
+Optional properties:
+ - dma-coherent: Enable ACHI coherency DMA operation.
+ - reg-names: register area names when there are more then 1 regster area.
+
+Examples:
+ sata@3200000 {
+ compatible = "fsl,ls1021a-ahci";
+ reg = <0x0 0x3200000 0x0 0x10000>;
+ interrupts = <GIC_SPI 101 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&platform_clk 1>;
+ dma-coherent;
+ };
