drivers: nrf: Enable nRF drivers by default in Kconfig Make the following nRF peripheral drivers: - ADC - GPIO - I2C - SPI - UART - USB_DEVICE enabled by default so that users do not need to explicitly enable them in their applications after choosing an nRF SoC as the build target. Kconfig options enabling these drivers depend on both a given hardware feature (e.g. I2C) and an nRF family SoC selected, so effectively they will be automatically enabled only when it is adequate (and in most cases these drivers are the only option for a given hardware feature on nRF SoCs).

drivers: gpio_nrfx: support edge interrupts using GPIO SENSE Currently level interrupts are implemented using GPIO SENSE, but edge interrupts using GPIOTE events. Using GPIOTE events results in increased power consumption according to product specifications and erratas of some nRF MCUs. In case of nRF52832 it is <20uA in System ON Idle and ~400-450uA when used in conjunction with SPI or TWI. Add a user configurable option to select between GPIOTE events and GPIO SENSE mechanism, for implementing edge interrupts. Selecting GPIO SENSE option will allow to reduce power consumption in scenarios mentioned by nRF MCUs erratas. Additionally GPIO SENSE mechanism (as opposed to GPIOTE event) allows to detect state changes of pins configured as output. Signed-off-by: Marcin Niestroj <m.niestroj@grinn-global.com>

help
Enable GPIO edge interrupts implementation using GPIOTE events.
config GPIO_NRF_INT_EDGE_USING_SENSE
bool "Edge interrupts using SENSE"
help
Enable GPIO edge interrupts implementation using GPIO SENSE, which is
a level interrupt mechanism. Conversion from level to edge interrupts
notification happens in GPIO driver, so it is transparent to GPIO
consumers after switching from GPIOTE mechanism.
Use this option as an alternative to GPIOTE event mechanism. According
to product specifications and erratas to some nRF MCUs, using GPIOTE
results in increased current consumption in System ON Idle and in
conjunction with SPI/TWI peripherals. Selecting this option allows to
reduce current for those cases.
Using this option additionally allows detecting state changes of pins
configured as output, which might be handy for some applications.
