Zephyr Debounce GPIO Input with interrupt.

[VadymS]

I work with Zephyr v1.5.1. PDK NRF5340.
I implemented interrupt from PB1 and sometimes I get double interrupt. 
1. Is input Debouncing supported in Zephyr?

2. How can I implement/change debouncing interval?

I tried to configurate the pin from "gpio_pin_configure" with flag "GPIO_INT_DEBOUNCE". I don't see the change in behavior.

It is possible to pass in the flag GPIO_INT_DEBOUNCE to gpio_pin_configure(). However, it does not seem like the gpio_nrfx.c driver supports it unfortunately. Check out the application nrf_desktop to see one example of how to implement debouncing: https://github.com/nrfconnect/sdk-nrf/blob/11fb11eb1cbda80e9a83806e5f5499f8ce6a2cc6/subsys/caf/modules/buttons.c#L414
