-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, ls1043a, ls1046a, ls1088a, ls2080a etc.
- - clocks: Input clock specifier. Refer to common clock bindings.
- - interrupts: Interrupt specifier. Refer to interrupt binding.
-
-Optional properties:
- - dma-coherent: Enable AHCI coherent DMA operation.
- - reg-names: register area names when there are more than 1 register area.
-
-Examples:
- sata@...0000 {
- compatible = "fsl,ls1021a-ahci";
- reg = <0x0 0x3200000 0x0 0x10000>;
- interrupts = <GIC_SPI 101 IRQ_TYPE_LEVEL_HIGH>;
- clocks = <&platform_clk 1>;
- dma-coherent;
- };
