Many thanks Lee ! Maybe I missed something, but just in case... In your pull request ("[GIT PULL] Immutable branch between MFD and PWM due for the v4.18 merge window") I only see 4 patches: Fabrice Gasnier (4): 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 I can't see patch 1 ("dt-bindings: mfd: stm32-timers: add support for dmas") Is it applied on another tree ?
