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 .../devicetree/bindings/mfd/stm32-timers.txt | 20 ++ arch/arm/boot/dts/stm32429i-eval.dts | 3 + drivers/mfd/stm32-timers.c | 215 +++++++++++++++- drivers/pwm/pwm-stm32.c | 276 ++++++++++++++++++++- include/linux/mfd/stm32-timers.h | 39 +++ 5 files changed, 547 insertions(+), 6 deletions(-) -- 1.9.1
