+* Clock bindings for Freescale Vybrid VF610 SOC
+
+Required properties:
+- compatible: Should be "fsl,vf610-ccm"
+- reg: Address and length of the register set
+- #clock-cells: Should be <1>
+
+Optional properties:
+- clocks: list of clock identifiers which are external input clocks to the
+       given clock controller. Please refer the next section to find
+       the input clocks for a given controller.
+- clock-names: list of names of clocks which are exteral input clocks to the
+       given clock controller.
+
+Input clocks for top clock controller:
+       - sxosc (external crystal oscillator 32KHz, recommended)
+       - fxosc (external crystal oscillator 24MHz, recommended)
+       - audio_ext
+       - enet_ext
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell. See include/dt-bindings/clock/vf610-clock.h
+for the full list of VF610 clock IDs.
+
+Examples:
+
+clks: ccm@4006b000 {
+       compatible = "fsl,vf610-ccm";
+       reg = <0x4006b000 0x1000>;
+       #clock-cells = <1>;
+       clocks = <&sxosc>, <&fxosc>;
+       clock-names = "sxosc", "fxosc";
+};
+
+uart1: serial@40028000 {
+       compatible = "fsl,vf610-uart";
+       reg = <0x40028000 0x1000>;
+       interrupts = <0 62 0x04>;
+       clocks = <&clks VF610_CLK_UART1>;
+       clock-names = "ipg";
+};
