+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.
+
+Example:
+ rootclk: clock-controller@1f801200 {
+ compatible = "microchip,pic32mzda-clk";
+ reg = <0x1f801200 0x200>;
+ #clock-cells = <1>;
+ /* optional */
+ microchip,pic32mzda-sosc;
+ };
+
+
+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>;
+};
