+* Clock bindings for Freescale i.MX1 CPUs
+
+Required properties:
+- compatible: Should be "fsl,imx1-ccm".
+- reg: Address and length of the register set.
+- #clock-cells: Should be <1>.
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx1-clock.h
+for the full list of i.MX1 clock IDs.
+
+Examples:
+	clks: ccm@0021b000 {
+		#clock-cells = <1>;
+		compatible = "fsl,imx1-ccm";
+		reg = <0x0021b000 0x1000>;
+	};
+
+	pwm: pwm@00208000 {
+		#pwm-cells = <2>;
+		compatible = "fsl,imx1-pwm";
+		reg = <0x00208000 0x1000>;
+		interrupts = <34>;
+		clocks = <&clks IMX1_CLK_DUMMY>, <&clks IMX1_CLK_PER1>;
+		clock-names = "ipg", "per";
+	};
