+* Clock bindings for Freescale i.MX5
+
+Required properties:
+- compatible: Should be "fsl,<soc>-ccm" , where <soc> can be imx51 or imx53
+- reg: Address and length of the register set
+- interrupts: Should contain CCM interrupt
+- #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/imx5-clock.h
+for the full list of i.MX5 clock IDs.
+
+Examples (for mx53):
+
+clks: ccm@53fd4000{
+       compatible = "fsl,imx53-ccm";
+       reg = <0x53fd4000 0x4000>;
+       interrupts = <0 71 0x04 0 72 0x04>;
+       #clock-cells = <1>;
+};
+
+can1: can@53fc8000 {
+       compatible = "fsl,imx53-flexcan", "fsl,p1010-flexcan";
+       reg = <0x53fc8000 0x4000>;
+       interrupts = <82>;
+       clocks = <&clks IMX5_CLK_CAN1_IPG_GATE>, <&clks IMX5_CLK_CAN1_SERIAL_GATE>;
+       clock-names = "ipg", "per";
+       status = "disabled";
+};
