   1 Microchip PIC32 Clock Controller Binding
   2 ----------------------------------------
   3 Microchip clock controller is consists of few oscillators, PLL, multiplexer
   4 and few divider modules.
   5
   6 This binding uses common clock bindings.

   9 Required properties:
  10 - compatible: shall be "microchip,pic32mzda-clk".
  11 - reg: shall contain base address and length of clock registers.
  12 - #clock-cells: shall be 1.
  13
  14 Optional properties:
  15 - microchip,pic32mzda-sosc: shall be added only if platform has
  16   secondary oscillator connected.
  17
  18 Example:
  19         rootclk: clock-controller@1f801200 {
  20                 compatible = "microchip,pic32mzda-clk";
  21                 reg = <0x1f801200 0x200>;
  22                 #clock-cells = <1>;
  23                 /* optional */
  24                 microchip,pic32mzda-sosc;
  25         };
  26
  27
  28 The clock consumer shall specify the desired clock-output of the clock
  29 controller (as defined in [2]) by specifying output-id in its "clock"
  30 phandle cell.

  33 For example for UART2:
  34 uart2: serial@2 {
  35         compatible = "microchip,pic32mzda-uart";
  36         reg = <>;
  37         interrupts = <>;
  38         clocks = <&rootclk PB2CLK>;
  39 };
