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 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 .../devicetree/bindings/mfd/st,stm32-lptimer.yaml | 21 ++ arch/arm/boot/dts/stm32mp151.dtsi | 35 ++++ arch/arm/mach-stm32/Kconfig | 1 + drivers/clocksource/Kconfig | 4 + drivers/clocksource/Makefile | 1 + drivers/clocksource/timer-stm32-lp.c | 221 +++++++++++++++++++++ drivers/mfd/stm32-lptimer.c | 1 + include/linux/mfd/stm32-lptimer.h | 5 + 8 files changed, 289 insertions(+) create mode 100644 drivers/clocksource/timer-stm32-lp.c -- 2.15.0
