- reg: Physical base address and size of the controller's register area.
|
|
- compatible: Compatibility string. Must be 'ceva,ahci-1v84'.
|
|
- clocks: Input clock specifier. Refer to common clock bindings.
|
|
- interrupts: Interrupt specifier. Refer to interrupt binding.
|
|
|

Examples:
|
|
ahci@fd0c0000 {
|
|
compatible = "ceva,ahci-1v84";
|
|
reg = <0xfd0c0000 0x200>;
|
|
interrupt-parent = <&gic>;
|
|
interrupts = <0 133 4>;
|
|
clocks = <&clkc SATA_CLK_ID>;
|
