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 ?

Best Regards,
Fabrice
