Merge tag 'rtc-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "The isl1208 dirver was reworked tobe able to work as part of an MFD.

  All the Loongson chips are now supported through a new driver, the old
  one is removed.

  Summary:

  Subsystem:
   - Switch i2c drivers back to use .probe()
   - Constify pointers to hwmon_channel_info

  New driver:
   - Loongson on chip RTC, replacing the Loongson 1 only driver

  Drivers:
   - isl1208: cleanup and support for RAA215300
   - st-lpc: cleanups
   - stm32: fix wakeup"
