Subject: Re: [PATCH v2 0/8] Add support for PWM input capture on STM32

2018-01-26 16:11 GMT+01:00 Fabrice Gasnier <fabrice.gasnier@...com>:
> 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.

> ---
> 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
