-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>;
-};
