+Device tree binding for the TI DM816 AHCI SATA Controller
+---------------------------------------------------------
+
+Required properties:
+ - compatible: must be "ti,dm816-ahci"
+ - reg: physical base address and size of the register region used by
+ the controller (as defined by the AHCI 1.1 standard)
+ - interrupts: interrupt specifier (refer to the interrupt binding)
+ - clocks: list of phandle and clock specifier pairs (or only
+ phandles for clock providers with '0' defined for
+ #clock-cells); two clocks must be specified: the functional
+ clock and an external reference clock
+
+Example:
+
+ sata: sata@4a140000 {
+ compatible = "ti,dm816-ahci";
+ reg = <0x4a140000 0x10000>;
+ interrupts = <16>;
+ clocks = <&sysclk5_ck>, <&sata_refclk>;
+ };
