Subject: [RESEND PATCH v2 0/8] Add support for PWM input capture on STM32
Date: Wed, 14 Feb 2018 11:04:31 +0100	[thread overview]
Message-ID: <1518602679-3064-1-git-send-email-fabrice.gasnier@st.com> (raw)

This series adds support for capture to stm32-pwm driver.
Capture is based on DMAs.
- First two patches are precursor patches
- Subsequent two patches add support for requesting DMAs to MFD core
- Next three patches add support for capture to stm32-pwm driver
- This has been tested on stm32429i-eval board.

---
Resend v2:
- Add collected Acks

Changes in v2:
- Abstract DMA handling from child driver: move it to MFD core
- Rework pwm capture routines to adopt this change
- Comment on optional dma support, beautify DMAs probe

Fabrice Gasnier (8):
  pwm: stm32: fix, remove unused struct device
  pwm: stm32: protect common prescaler for all channels
  dt-bindings: mfd: stm32-timers: add support for dmas
  mfd: stm32-timers: add support for dmas
  pwm: stm32: add capture support
  pwm: stm32: improve capture by tuning counter prescaler
  pwm: stm32: use input prescaler to improve period capture
  ARM: dts: stm32: Enable pwm3 input capture on stm32f429i-eval
