   1 * Microchip PIC32 Clock and Oscillator
   2
   3 Microchip PIC32 clock tree consists of few oscillators, PLLs,
   4 multiplexers and few divider modules capable of supplying clocks
   5 to various controllers within SoC and also to off-chip.
   6
   7 PIC32 clock controller output is defined by indices as defined
   8 in [0]

  10 [0] include/dt-bindings/clock/microchip,clock.h
  11
  12 Required Properties:
  13 - compatible: should be "microchip,pic32mzda_clk"
  14 - reg: physical base address of the controller and length of memory mapped
  15        region.
  16 - #clock-cells: should be 1.

  18 Example: Clock controller node:
  19
  20         clock: clk@1f801200 {
  21                 compatible = "microchip,pic32mzda-clk";
  22                 reg = <0x1f801200 0x1000>;
  23         };
  24
  25 Example: UART controller node that consumes the clock generated by the clock
  26 controller:
  27
  28         uart1: serial@1f822000 {
  29                 compatible = "microchip,pic32mzda-uart";
  30                 reg = <0xbf822000 0x50>;
  31                 interrupts = <112 IRQ_TYPE_LEVEL_HIGH>;
  32                 clocks = <&clock PB2CLK>;
  33         };
