-* 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";

-	interrupts = <82>;
-	clocks = <&clks IMX5_CLK_CAN1_IPG_GATE>, <&clks IMX5_CLK_CAN1_SERIAL_GATE>;
-	clock-names = "ipg", "per";
-};
