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 Benjamin Gaignard (3): dt-bindings: mfd: Document STM32 low power timer bindings mfd: stm32: Add defines to be used for clkevent purpose clocksource: Add Low Power STM32 timers driver .../devicetree/bindings/mfd/st,stm32-lptimer.yaml | 16 ++ drivers/clocksource/Kconfig | 7 + drivers/clocksource/Makefile | 1 + drivers/clocksource/timer-stm32-lp.c | 213 +++++++++++++++++++++ include/linux/mfd/stm32-lptimer.h | 5 + 5 files changed, 242 insertions(+) create mode 100644 drivers/clocksource/timer-stm32-lp.c -- 2.15.0
