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.
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
