Subject: [PATCH v2 0/3] Add PM support to STM32 LP Timer drivers

This patch series adds power management support for STM32 LP Timer:
- PWM driver
- Document the pinctrl states for sleep mode

It also adds device link between the PWM consumer and the PWM provider.
This allows proper sequencing for suspend/resume (e.g. user will likely
do a pwm_disable() before the PWM provider suspend executes), see [1].

Changes in v2:
- Don't disable PWM channel in PWM provider: rather refuse to suspend
  and report an error as suggested by Uwe and Thierry.
- Add patch 3/3 to propose device link addition.
- No updates for STM32 LP Timer IIO driver. Patches can be send separately.
