[PATCH v4 0/5] gpio: add suspend/resume support for i.mx8x SoCs

> Subject: [PATCH v4 0/5] gpio: add suspend/resume support for i.mx8x SoCs
> 
> On i.MX8QM/QXP/DXL SoCs, even a GPIO is selected as the wakeup source, the
> GPIO block will be powered off when system enters into suspend state. This can
> greatly reduce the power consumption of suspend state because the whole
> partition can be shutdown. This is called PAD wakeup feature on i.MX8x
> platform.
> 
> This series of patches enable this wakeup feature on i.MX8QM/QXP/DXL
> platforms.
> 
> Changes in v4:
>  - fixed the format issues reported by Peng Fan.
>  - change the return type of mxc_gpio_generic_config, and limit the
>    suspend/resume behavior changes only on i.MX8QM/QXP/DXL platform.

A soft ping. 😊

> Changes in v3:
>  - According to the feedback from Linus Walleij, the wakeup feature is
>    moved to pinctrl driver, and the array of gpio-pin mapping is moved
>    to gpio device node and initialized via gpio-ranges property.
