Subject: [PATCH v2 0/3] rtc: isl12022: Add alarm support

Extend the rtc-isl12022 driver with alarm IRQ support.

Signed-off-by: Esben Haabendal <esben@...nix.com>
---
Changes in v2:
- Various coding style changes.
- Remove const keyword from auto variable declaration.
- Use u8 type instead of uint8_t.
- Fixed bad return value in isl12022_rtc_read_alarm() error handling.
- Change variable type from int to unsigned int for variable given to
  regmap_read().
- Drop unneeded variable initialization (ret) in
  isl12022_rtc_set_alarm().
- Extend use of DWA0 variable to avoid false alarm trigger also when
  disabling alarm.
- Clarify the use of !! operator in isl12022_rtc_alarm_irq_enable().
- Change isl12022_setup_irq() prototype to avoid the need for storing
  struct i2c_client in struct isl12022.
- Use dev_err_probe() where appropriate.
- Change dev_err messages reporting problems with register access into
  dev_dbg.
- Renamed ISL12022_ALARM_SECTION to ISL12022_ALARM for better use of
  horizontal space.
- Leave FOBATB bit untouched.
- Link to v1: https://lore.kernel.org/r/20240910-rtc-isl12022-alarm-irq-v1-0-d875cedc997f@geanix.com
