+* 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 source clk. Should be <&rootclk PB7CLK>.
+
+Example:
+
+	watchdog@1f800a00 {
+		compatible = "microchip,pic32mzda-dmt";
+		reg = <0x1f800a00 0x80>;
+		clocks = <&rootclk PB7CLK>;

+* Microchip PIC32 Watchdog Timer

+When enabled, the watchdog peripheral can be used to reset the device if the

+Renesas Watchdog Timer (WDT) Controller
+
+Required properties:
+- compatible : Should be "renesas,r8a7795-wdt", or "renesas,rcar-gen3-wdt"
+
+  When compatible with the generic version, nodes must list the SoC-specific
+  version corresponding to the platform first, followed by the generic
+  version.
+
+- reg : Should contain WDT registers location and length
+- clocks : the clock feeding the watchdog timer.
+
+Optional properties:
+- timeout-sec : Contains the watchdog timeout in seconds
+- power-domains : the power domain the WDT belongs to
+
+Examples:
+
+	wdt0: watchdog@e6020000 {
+		compatible = "renesas,r8a7795-wdt", "renesas,rcar-gen3-wdt";
+		reg = <0 0xe6020000 0 0x0c>;
+		clocks = <&cpg CPG_MOD 402>;
+		power-domains = <&cpg>;
+		timeout-sec = <60>;
