Subject: [PATCH v4 0/3] clockevent: add low power STM32 timer
Date: Mon, 17 Feb 2020 14:45:43 +0100	[thread overview]
Message-ID: <20200217134546.14562-1-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 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
