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"

-Intersil ISL1209/19 I2C RTC/Alarm chip with event in
-
-ISL12X9 have additional pins EVIN and #EVDET for tamper detection, while the
-ISL1208 and ISL1218 do not.  They are all use the same driver with the bindings
-described here, with chip specific properties as noted.
-
-Required properties supported by the device:
- - "compatible": Should be one of the following:
-		- "isil,isl1208"
-		- "isil,isl1209"
-		- "isil,isl1218"
-		- "isil,isl1219"
- - "reg": I2C bus address of the device
-
-Optional properties:
- - "interrupt-names": list which may contains "irq" and "evdet"
-	evdet applies to isl1209 and isl1219 only
- - "interrupts": list of interrupts for "irq" and "evdet"
-	evdet applies to isl1209 and isl1219 only
- - "isil,ev-evienb": Enable or disable internal pull on EVIN pin
-	Applies to isl1209 and isl1219 only
-	Possible values are 0 and 1
-	Value 0 enables internal pull-up on evin pin, 1 disables it.
-	Default will leave the non-volatile configuration of the pullup
-	as is.
-
-Example isl1219 node with #IRQ pin connected to SoC gpio1 pin12 and #EVDET pin
-connected to SoC gpio2 pin 24 and internal pull-up enabled in EVIN pin.
