1*c66ec88fSEmmanuel Vadot* Microchip PIC32 Real Time Clock and Calendar
2*c66ec88fSEmmanuel Vadot
3*c66ec88fSEmmanuel VadotThe RTCC keeps time in hours, minutes, and seconds, and one half second. It
4*c66ec88fSEmmanuel Vadotprovides a calendar in weekday, date, month, and year. It also provides a
5*c66ec88fSEmmanuel Vadotconfigurable alarm.

7*c66ec88fSEmmanuel VadotRequired properties:
8*c66ec88fSEmmanuel Vadot- compatible: should be: "microchip,pic32mzda-rtc"
9*c66ec88fSEmmanuel Vadot- reg: physical base address of the controller and length of memory mapped
10*c66ec88fSEmmanuel Vadot    region.
11*c66ec88fSEmmanuel Vadot- interrupts: RTC alarm/event interrupt
12*c66ec88fSEmmanuel Vadot- clocks: clock phandle
