Subject: [PATCH v3 0/6] Add support for PWM input capture on STM32
Date: Fri, 30 Mar 2018 12:01:18 +0200 [thread overview]
Message-ID: <1522404084-24903-1-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 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.
---
Changes in v3:
- Dropped 2 precusor patches applied by Thierry in pwm tree:
"pwm: stm32: fix, remove unused struct device"
"pwm: stm32: protect common prescaler for all channels"
- Note: this series applies on top on pwm tree
- Implements Lee's comments on MFD part: rework stm32_timers_dma struct,
exported routine prototype now use generic device struct, more
various comments (see patch 2 changelog).
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 (6):
dt-bindings: mfd: stm32-timers: add support for dmas
