-* Microchip PIC32 Real Time Clock and Calendar
-
-The RTCC keeps time in hours, minutes, and seconds, and one half second. It
-provides a calendar in weekday, date, month, and year. It also provides a
-configurable alarm.
-
-Required properties:
-- compatible: should be: "microchip,pic32mzda-rtc"
-- reg: physical base address of the controller and length of memory mapped
-    region.
-- interrupts: RTC alarm/event interrupt
-- clocks: clock phandle
-
-Example:
-
-	rtc: rtc@1f8c0000 {
-		compatible = "microchip,pic32mzda-rtc";
-		reg = <0x1f8c0000 0x60>;
-		interrupts = <166 IRQ_TYPE_EDGE_RISING>;
-		clocks = <&PBCLK6>;
-	};
