This series adds initial support for the NXP PCF8525 real-time clock.
The NXP PCF8525 is an I2C RTC with the following features:
- Time/date keeping (seconds to years, BCD encoded)
- Alarm with interrupt support on INTA
- Two hardware timestamps (TS1/TS2) exposed via sysfs
- Crystal aging offset correction via the RTC offset interface
- Battery backup with configurable backup switch mode (BSM)
- Optional watchdog timer on INTB
- Optional temperature sensor via hwmon
Patch 1 adds the devicetree binding document (YAML schema).
Patch 2 adds the core RTC driver with time, alarm, timestamp,
aging offset, and backup switch mode support.
Patch 3 adds optional watchdog support via Watchdog Core on INTB.
Patch 4 adds optional temperature sensor support via hwmon.
