[PATCH v2 0/4] Add support for STM32 TIMERS and STM32 PWM

[Cheick Traore]

This serie adds:
* drivers for MFD STM32 TIMERS and STM32 PWM, the driver split is
  inspired by kernel model
* enable these drivers on stm32mp13 for PWM backlight available on
  stm32mp135f-dk
* timer node, pwm subnode and pinctrl for PWM Backlight on
  stm32mp135f-dk

Changes in v2:
- remove pwm-uclass patch because some drivers already manage the config
  in case the duty_ns exceeds period_ns
- add the check of duty_ns and period_ns parameters in pwm-stm32 driver

Cheick Traore (4):
  mach-stm32: add multifunction timer driver support
  pwm: stm32: add driver to support pwm with timer
  configs: stm32mp13: Enable MFD timer and PWM for stm32mp13_defconfig
  ARM: dts: stm32: Add TIMERS inverted PWM channel 3 on STM32MP135F-DK
