dt-bindings: clk: intel: Add bindings document & header file for CGU 



Clock generation unit(CGU) is a clock controller IP of Intel's Lightning
Mountain(LGM) SoC. Add DT bindings include file and document for CGU clock
controller driver of LGM.

title: Intel Lightning Mountain SoC's Clock Controller(CGU) Binding



maintainers:

  - Rahul Tanwar <rahul.tanwar@linux.intel.com>



description: |

  Lightning Mountain(LGM) SoC's Clock Generation Unit(CGU) driver provides

  all means to access the CGU hardware module in order to generate a series

  of clocks for the whole system and individual peripherals.



  Please refer to include/dt-bindings/clock/intel,lgm-clk.h header file, it

  defines all available clocks as macros. These macros can be used in device

  tree sources.



properties:

  compatible:

    const: intel,cgu-lgm



  reg:

    maxItems: 1



  '#clock-cells':

    const: 1



required:

  - compatible

  - reg

  - '#clock-cells'



examples:

  - |

    cgu: clock-controller@e0200000 {

        compatible = "intel,cgu-lgm";

        reg = <0xe0200000 0x33c>;

        #clock-cells = <1>;

    };
