* Clock bindings for NXP i.MX8M Mini



Required properties:

- compatible: Should be "fsl,imx8mm-ccm"

- reg: Address and length of the register set

- #clock-cells: Should be <1>

- clocks: list of clock specifiers, must contain an entry for each required

          entry in clock-names

- clock-names: should include the following entries:

    - "osc_32k"

    - "osc_24m"

    - "clk_ext1"

    - "clk_ext2"

    - "clk_ext3"

    - "clk_ext4"



clk: clock-controller@30380000 {

	compatible = "fsl,imx8mm-ccm";

	reg = <0x0 0x30380000 0x0 0x10000>;

	#clock-cells = <1>;

	clocks = <&osc_32k>, <&osc_24m>, <&clk_ext1>, <&clk_ext2>,

		 <&clk_ext3>, <&clk_ext4>;

	clock-names = "osc_32k", "osc_24m", "clk_ext1", "clk_ext2",

		      "clk_ext3", "clk_ext4";

};



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

ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx8mm-clock.h

for the full list of i.MX8M Mini clock IDs.
