+Binding for CEVA AHCI SATA Controller
+
+Required properties:
+ - 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.
+
+Optional properties:
+ - ceva,broken-gen2: limit to gen1 speed instead of gen2.
+
+Examples:
+ ahci@fd0c0000 {
+ compatible = "ceva,ahci-1v84";
+ reg = <0xfd0c0000 0x200>;
+ interrupt-parent = <&gic>;
+ interrupts = <0 133 4>;
+ clocks = <&clkc SATA_CLK_ID>;
+ ceva,broken-gen2;
