This series add low power timer as boadcast clockevent device.
Low power timer could runs even when CPUs are in idle mode and 
could wakeup them.

Lee has acked the MFD part.
Clocksource driver still need to be reviewed by maintainers.
Add missing part of the bindings to describe interrupt.

version 7:
- rebased on top of v5.7-rc2

version 6:
- simplify binding, DT and code to use only one interrupt

version 5:
- document interrupts and interrupt-names bindings
- use a different wake up interrupt
- add device-tree patch
- make STM32MP157 select low power timer configuration flag
- enable fast_io in regmap configuration

version 4:
- move defines in mfd/stm32-lptimer.h
- change compatible and subnode names
- document wakeup-source property
- reword commit message
- make driver Kconfig depends of MFD_STM32_LPTIMER
- remove useless include
- remove rate and clk fields from the private structure
- to add comments about the registers sequence in stm32_clkevent_lp_set_timer
- rework probe function and use devm_request_irq()
- do not allow module to be removed

version 3:
- fix timer set sequence
- don't forget to free irq on remove function
- use devm_kzalloc to simplify errors handling in probe function

version 2:
- stm32 clkevent driver is now a child of the stm32 lp timer node
- add a probe function and adpat the driver to use regmap provide
  by it parent
- stop using timer_of helpers


Benjamin Gaignard (6):
  dt-bindings: mfd: Document STM32 low power timer bindings
  ARM: dts: stm32: Add timer subnodes on stm32mp15 SoCs
  mfd: stm32: Add defines to be used for clkevent purpose
  mfd: stm32: enable regmap fast_io for stm32-lptimer
  clocksource: Add Low Power STM32 timers driver
  ARM: mach-stm32: select low power timer for STM32MP157
