Kernel-4.18.0-80.el8_nxp,lpc3220-clk

NXP LPC32xx Clock Controller

Required properties:

• compatible: should be “nxp,lpc3220-clk”
• reg: should contain clock controller registers location and length
• #clock-cells: must be 1, the cell holds id of a clock provided by the
  clock controller
• clocks: phandles of external oscillators, the list must contain one
  32768 Hz oscillator and may have one optional high frequency oscillator
• clock-names: list of external oscillator clock names, must contain
  “xtal_32k” and may have optional “xtal”

Examples:

/* System Control Block */
scb {
    compatible = "simple-bus";
    ranges = <0x0 0x040004000 0x00001000>;
    #address-cells = <1>;
    #size-cells = <1>;

    clk: clock-controller@0 {
        compatible = "nxp,lpc3220-clk";
        reg = <0x00 0x114>;
        #clock-cells = <1>;

        clocks = <&xtal_32k>, <&xtal>;
        clock-names = "xtal_32k", "xtal";
    };
};
