    1 * Clock bindings for Freescale Vybrid VF610 SOC
    2 
    3 Required properties:
    4 - compatible: Should be "fsl,vf610-ccm"
    5 - reg: Address and length of the register set
    6 - #clock-cells: Should be <1>
    7 
    8 Optional properties:
    9 - clocks: list of clock identifiers which are external input clocks to the
   10         given clock controller. Please refer the next section to find
   11         the input clocks for a given controller.
   12 - clock-names: list of names of clocks which are exteral input clocks to the
   13         given clock controller.
   14 
   15 Input clocks for top clock controller:
   16         - sxosc (external crystal oscillator 32KHz, recommended)
   17         - fxosc (external crystal oscillator 24MHz, recommended)
   18         - audio_ext
   19         - enet_ext
   20 
   21 The clock consumer should specify the desired clock by having the clock
   22 ID in its "clocks" phandle cell. See include/dt-bindings/clock/vf610-clock.h
   23 for the full list of VF610 clock IDs.
   24 
   25 Examples:
   26 
   27 clks: ccm@4006b000 {
   28         compatible = "fsl,vf610-ccm";
   29         reg = <0x4006b000 0x1000>;
   30         #clock-cells = <1>;
   31         clocks = <&sxosc>, <&fxosc>;
   32         clock-names = "sxosc", "fxosc";
   33 };
   34 
   35 uart1: serial@40028000 {
   36         compatible = "fsl,vf610-uart";
   37         reg = <0x40028000 0x1000>;
   38         interrupts = <0 62 0x04>;
   39         clocks = <&clks VF610_CLK_UART1>;
   40         clock-names = "ipg";
   41 };
