Subject: [PATCH 0/8] Add STM32MP25 LPTIM support: MFD, PWM, IIO, counter, clocksource

This series adds support for STM32MP25 to MFD PWM, IIO, counter and
clocksource low-power timer (LPTIM) drivers.
This new 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.
Same feature list as on STM32MP1x is supported currently.
The device tree files add all instances in stm32mp251 dtsi file.

Fabrice Gasnier (6):
  dt-bindings: mfd: stm32-lptimer: add support for stm32mp25
  mfd: stm32-lptimer: add support for stm32mp25
  pwm: stm32-lp: add support for stm32mp25
  counter: stm32-lptimer-cnt: add support for stm32mp25
  arm64: defconfig: enable STM32 LP timers drivers
  arm64: dts: st: add low-power timer nodes on stm32mp251

Olivier Moysan (1):
  iio: trigger: stm32-lptimer: add support for stm32mp25

Patrick Delaunay (1):
  clocksource: stm32-lptimer: add stm32mp25 support
