This series delivers power improvements for stm32-usart driver.

Bich Hemon (4):
  dt-bindings: serial: add optional pinctrl states
  serial: stm32: select pinctrl state in each suspend/resume function
  ARM: dts: stm32: Update pin states for uart4 on stm32mp157c-ed1
  ARM: dts: stm32: Update UART4 pin states on stm32mp157a-dk1

Erwan Le Ray (6):
  dt-bindings: serial: stm32: add wakeup option
  serial: stm32: add pm_runtime support
  serial: stm32: Use __maybe_unused instead of #if CONFIG_PM_SLEEP
  serial: stm32: add support for no_console_suspend
  ARM: dts: stm32: update uart4 pin configurations for low power
  ARM: dts: stm32: add wakeup capability on each usart/uart on
    stm32mp157c

I'll merge device tree part into stm32-next branch when binding part 
will be accepted.
