* 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.
