help
This option enables wake up from deep sleep using touch pads.
ESP32 - TOUCH8 and TOUCH9, which correspond to GPIO33 and GPIO32.
ESP32S2/S3 - TOUCH9, which corresponds to GPIO9.
Note: On ESP32, touch wakeup source can not be used together with ext0 wakeup source.

depends on SOC_PM_SUPPORT_EXT0_WAKEUP
help
This option enables wake up from deep sleep from GPIO25(ESP32)/GPIO3(ESP32S2,S3). The pin should be
connected to LOW to avoid being in a floating state. When triggering a wake up, connect the pin to HIGH.
Note that floating pins may trigger a wake up.
Note: On ESP32, ext0 wakeup source can not be used together with touch wakeup source.

help
This option enables wake up from deep sleep from GPIO2 and GPIO4. They should be connected to LOW to avoid
floating pins. When triggering a wake up, connect one or both of the pins to HIGH. Note that floating
pins may trigger a wake up.
config EXAMPLE_EXT1_USE_INTERNAL_PULLUPS
bool "Use internal pull-up/downs for EXT1 wakeup source"
default n
depends on EXAMPLE_EXT1_WAKEUP
help
When using EXT1 wakeup source without external pull-up/downs, you may want to make use of the internal
ones.
However, the RTC IO reside in the RTC Periph power domain. Enable this option to force that power domain
ON during deep sleep. Note that this will increase some power comsumption, so it's still suggested to use
external ones instead.
EXT0 wakeup source resides in the same power domain as RTCIO (RTC Periph), so internal pull-up/downs are
always available. There's no need to explicitly force it on for EXT0.
config EXAMPLE_GPIO_WAKEUP
bool "Enable wakeup from GPIO"
default y
depends on SOC_GPIO_SUPPORT_DEEPSLEEP_WAKEUP
help
This option enables wake up from GPIO. Be aware that if you use low level to trigger wakeup, we strongly
recommand you to connect external pull-up resistance.

This option set the gpio wake-up trigger signal, In deep sleep, only high or low level wake-up is
supported. If this option is enabled, it is a high level wake up, otherwise it is a low level wake up.
