+Binding for Texas Instruments clockdomain.
+
+This binding uses the common clock binding[1]. Every clock on
+TI SoC belongs to one clockdomain, but software only needs this
+information for specific clocks which require their parent
+clockdomain to be controlled when the clock is enabled/disabled.
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be "ti,clockdomain"
+- #clock-cells : from common clock binding; shall be set to 0.
+- clocks : link phandles of clocks within this domain
+
+Examples:
+	dss_clkdm: dss_clkdm {
+		compatible = "ti,clockdomain";
+		clocks = <&dss1_alwon_fck_3430es2>, <&dss_ick_3430es2>;
+	};
