Add a new stm32mp25 compatible to stm32-lptimer dt-bindings, to support STM32MP25 SoC. Some features has been updated or added to the low-power timer: - new capture compare channels - up to two PWM channels - PWM input capture - peripheral interconnect in stm32mp25 has been updated (new triggers). - registers/bits has been added or revisited (IER access). So introduce a new compatible to handle this diversity.
