[Linux-stm32] [PATCH 0/2] pinctrl: stm32: add suspend/resume management

[Alexandre Torgue]

During power sequence, GPIO hardware registers could be lost if the power
supply is switched off. Each device using pinctrl API is in charge of
managing pins during suspend/resume sequences. But for pins used as gpio or
irq stm32 pinctrl driver has to save the hardware configuration.
Each register will be saved at runtime and restored during resume sequence.

Alex
