Since commit 502df79b86 ("gpiolib: Warn on drivers still using static
gpiobase allocation"), one or more warnings are printed during boot on
systems where static allocation of GPIO base is used:
[ 0.197707] gpio gpiochip0: Static allocation of GPIO base is deprecated, use dynamic allocation.
[ 0.199942] stm32f429-pinctrl soc:pinctrl@40020000: GPIOA bank added
[ 0.200711] gpio gpiochip1: Static allocation of GPIO base is deprecated, use dynamic allocation.
[ 0.202855] stm32f429-pinctrl soc:pinctrl@40020000: GPIOB bank added
[ 0.203591] gpio gpiochip2: Static allocation of GPIO base is deprecated, use dynamic allocation.
[ 0.205704] stm32f429-pinctrl soc:pinctrl@40020000: GPIOC bank added
[ 0.206338] gpio gpiochip3: Static allocation of GPIO base is deprecated, use dynamic allocation.
[ 0.208448] stm32f429-pinctrl soc:pinctrl@40020000: GPIOD bank added
[ 0.209182] gpio gpiochip4: Static allocation of GPIO base is deprecated, use dynamic allocation.
[ 0.211282] stm32f429-pinctrl soc:pinctrl@40020000: GPIOE bank added
[ 0.212094] gpio gpiochip5: Static allocation of GPIO base is deprecated, use dynamic allocation.
[ 0.214270] stm32f429-pinctrl soc:pinctrl@40020000: GPIOF bank added
[ 0.215005] gpio gpiochip6: Static allocation of GPIO base is deprecated, use dynamic allocation.
[ 0.217110] stm32f429-pinctrl soc:pinctrl@40020000: GPIOG bank added
[ 0.217845] gpio gpiochip7: Static allocation of GPIO base is deprecated, use dynamic allocation.
[ 0.219959] stm32f429-pinctrl soc:pinctrl@40020000: GPIOH bank added
[ 0.220602] gpio gpiochip8: Static allocation of GPIO base is deprecated, use dynamic allocation.
[ 0.222714] stm32f429-pinctrl soc:pinctrl@40020000: GPIOI bank added
[ 0.223483] gpio gpiochip9: Static allocation of GPIO base is deprecated, use dynamic allocation.
[ 0.225594] stm32f429-pinctrl soc:pinctrl@40020000: GPIOJ bank added
[ 0.226336] gpio gpiochip10: Static allocation of GPIO base is deprecated, use dynamic allocation.
[ 0.228490] stm32f429-pinctrl soc:pinctrl@40020000: GPIOK bank added
So let's follow the suggestion and use dynamic allocation.
Tested on STM32F429I-DISC1 board.
