This series adds STM32MP25 support on MFD PWM, IIO, counter timer drivers.
This new timer variant is managed by using a new DT compatible string.
It comes with a slightly updated register set, some new features and new
interconnect signals inside the SoC. There is also a new instance (TIM20).
Same feature list as on STM32MP1x is supported currently, except for PWM
capture (not enabled, by DT).
The device tree files add all instances in stm32mp251 dtsi. PWM, counter
and trigger examples are provided for stm32mp257f-ev1 board.
