[PATCH 1/2] dt/bindings: Add bindings for PIC32 deadman timer peripheral

[Joshua Henderson]

From: Purna Chandra Mandal <purna.mandal-UWL1GkI3JZL3oGB3hsPCZA@public.gmane.org>

Document the devicetree bindings for the deadman timer peripheral found on
Microchip PIC32 SoC class devices.

+* Microchip PIC32 Deadman Timer
+
+The deadman timer is used to reset the processor in the event of a software
+malfunction. It is a free-running instruction fetch timer, which is clocked
+whenever an instruction fetch occurs until a count match occurs.
+
+Required properties:
+- compatible: must be "microchip,pic32mzda-dmt".
+- reg: physical base address of the controller and length of memory mapped
+  region.
+- clocks: phandle of parent clock (should be &PBCLK7).
+
+Example:
+
+	watchdog2: dmt@1f800a00 {
+		compatible = "microchip,pic32mzda-dmt";
+		reg = <0x1f800a00 0x80>;
+		clocks = <&PBCLK7>;
+	};

    The node names should be generic, i.e. "watchdog" in this case.
