* The mapping of wake-up line WKUP2, WKUP5 and WKUP6 to GPIO pins depends on
* the pin count of the SoC installed on a given board. Board DTS files are
* responsible for configuring these lines using the following snippet
* (which must be adapted depending on the board's SoC):
*
* &pwr {
* wkup-pin@2 {
* wkup-gpios = <&gpioX YY STM32_PWR_WKUP_PIN_NOT_MUXED>;
* };
* wkup-pin@5 {
* wkup-gpios = <&gpioX YY STM32_PWR_WKUP_PIN_NOT_MUXED>;
* };
* wkup-pin@6 {
* wkup-gpios = <&gpioX YY STM32_PWR_WKUP_PIN_NOT_MUXED>;
* };
* };
*
* Refer to product Datasheet §4 "Pinouts, pin description and alternate functions"
* for information about which GPIO pin (if any) is connected to wake-up lines WKUP2,
* WKUP5 and WKUP6. The following table provides a summary:
*
* Part Number |- WKUP2 -|- WKUP5 -|- WKUP6 -|
