+Device tree binding for the TI DA850 AHCI SATA Controller
+---------------------------------------------------------
+
+Required properties:
+  - compatible: must be "ti,da850-ahci"
+  - reg: physical base addresses and sizes of the controller's register areas
+  - interrupts: interrupt specifier (refer to the interrupt binding)
+
+Optional properties:
+  - clocks: clock specifier (refer to the common clock binding)
+  - da850,clk_multiplier: the multiplier for the reference clock needed
+                          for 1.5GHz PLL output
+
+Example:
+
+	sata: ahci@...18000 {
+		compatible = "ti,da850-ahci";
+		reg = <0x218000 0x2000>, <0x22c018 0x4>;
+		interrupts = <67>;
+		da850,clk_multiplier = <7>;
+	};
