Subject: [PATCH v6 0/6] clockevent: add low power STM32 timer
Date: Wed, 1 Apr 2020 10:39:03 +0200 [thread overview]
Message-ID: <20200401083909.18886-1-benjamin.gaignard@st.com> (raw)
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
