Microchip PIC32 Clock Controller Binding
Microchip clock controller is consists of few oscillators, PLL, multiplexer
and few divider modules.
This binding uses common clock bindings.
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
Required properties:
- compatible: shall be "microchip,pic32mzda-clk".
- reg: shall contain base address and length of clock registers.
- #clock-cells: shall be 1.
Optional properties:
- microchip,pic32mzda-sosc: shall be added only if platform has
secondary oscillator connected.
rootclk: clock-controller@1f801200 {
compatible = "microchip,pic32mzda-clk";
reg = <0x1f801200 0x200>;
#clock-cells = <1>;
/* optional */
The clock consumer shall specify the desired clock-output of the clock
controller (as defined in [2]) by specifying output-id in its "clock"
phandle cell.
[2] include/dt-bindings/clock/microchip,pic32-clock.h
For example for UART2:
uart2: serial@2 {
compatible = "microchip,pic32mzda-uart";
reg = <>;
interrupts = <>;
clocks = <&rootclk PB2CLK>;
