    1 NXP LPC32xx Clock Controller
    2 
    3 Required properties:
    4 - compatible: should be "nxp,lpc3220-clk"
    5 - reg:  should contain clock controller registers location and length
    6 - #clock-cells: must be 1, the cell holds id of a clock provided by the
    7   clock controller
    8 - clocks: phandles of external oscillators, the list must contain one
    9   32768 Hz oscillator and may have one optional high frequency oscillator
   10 - clock-names: list of external oscillator clock names, must contain
   11   "xtal_32k" and may have optional "xtal"
   12 
   13 Examples:
   14 
   15         /* System Control Block */
   16         scb {
   17                 compatible = "simple-bus";
   18                 ranges = <0x0 0x040004000 0x00001000>;
   19                 #address-cells = <1>;
   20                 #size-cells = <1>;
   21 
   22                 clk: clock-controller@0 {
   23                         compatible = "nxp,lpc3220-clk";
   24                         reg = <0x00 0x114>;
   25                         #clock-cells = <1>;
   26 
   27                         clocks = <&xtal_32k>, <&xtal>;
   28                         clock-names = "xtal_32k", "xtal";
   29                 };
   30         };
