+* Microchip PIC32 Clock and Oscillator
+
+Microchip PIC32 clock tree consists of few oscillators, PLLs,
+multiplexers and few divider modules capable of supplying clocks
+to various controllers within SoC and also to off-chip.
+
+PIC32 clock controller output is defined by indices as defined
+in [0]
+
+[0] include/dt-bindings/clock/microchip,clock.h
+
+Required Properties:
+- compatible: should be "microchip,pic32mzda_clk"
+- reg: physical base address of the controller and length of memory mapped
+       region.
+- #clock-cells: should be 1.
+
+Example: Clock controller node:
+
+	clock: clk@1f801200 {
+		compatible = "microchip,pic32mzda-clk";
+		reg = <0x1f801200 0x1000>;
+	};
+
+Example: UART controller node that consumes the clock generated by the clock
+controller:
+
+	uart1: serial@1f822000 {
+		compatible = "microchip,pic32mzda-uart";
+		reg = <0xbf822000 0x50>;
+		interrupts = <112 IRQ_TYPE_LEVEL_HIGH>;
+		clocks = <&clock PB2CLK>;
+	};
