-* 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@21b000 {
-		#clock-cells = <1>;
-		compatible = "fsl,imx1-ccm";
-		reg = <0x0021b000 0x1000>;

-
-	pwm: pwm@208000 {
-		#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";
