dt-bindings: clk: imx: Add fsl,scu-clk yaml file 



In order to replace the fsl,scu txt file from bindings/arm/freescale,
we need to split it between the right subsystems. This patch documents
separately the 'clock' child node of the SCU main node.

Clock bindings based on SCU Message Protocol

------------------------------------------------------------



This binding uses the common clock binding[1].



Required properties:

- compatible:		Should be one of:

			  "fsl,imx8dxl-clk"

			  "fsl,imx8qm-clk"

			  "fsl,imx8qxp-clk"

			followed by "fsl,scu-clk"

- #clock-cells:		Should be 2.

			Contains the Resource and Clock ID value.

- clocks:		List of clock specifiers, must contain an entry for

			each required entry in clock-names

- clock-names:		Should include entries "xtal_32KHz", "xtal_24MHz"



The clock consumer should specify the desired clock by having the clock

ID in its "clocks" phandle cell.

description: i.MX SCU Client Device Node

  Client nodes are maintained as children of the relevant IMX-SCU device node.

  This binding uses the common clock binding.

  (Documentation/devicetree/bindings/clock/clock-bindings.txt)

  The clock consumer should specify the desired clock by having the clock

  ID in its "clocks" phandle cell. See the full list of clock IDs from

  include/dt-bindings/clock/imx8qxp-clock.h



properties:

  compatible:

    items:

      - enum:

          - fsl,imx8dxl-clk

          - fsl,imx8qm-clk

          - fsl,imx8qxp-clk

      - const: fsl,scu-clk



  '#clock-cells':

    const: 2



required:

  - compatible

  - '#clock-cells'



additionalProperties: false



examples:

  - |

    clock-controller {

        compatible = "fsl,imx8qxp-clk", "fsl,scu-clk";

        #clock-cells = <2>;
