Move pinctrl/consumer.h include from "add support for no_console_suspend"
patch to "select pinctrl state" patch in order to solve a compilation
issue.
Bich Hemon (3):
dt-bindings: serial: add optional pinctrl states
ARM: dts: stm32: Update pin states for uart4 on stm32mp157c-ed1
ARM: dts: stm32: Update UART4 pin states on stm32mp157a-dk1
Erwan Le Ray (7):
dt-bindings: serial: stm32: add wakeup option
serial: stm32: select pinctrl state in each suspend/resume function
serial: stm32: add pm_runtime support
