Disable nrf9160 GPIO pins before sleep

[Tron]

I'm looking at the GPIO functions in http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/reference/peripherals/gpio.html, and looking at the function prototype 

static int gpio_pin_configure(structdevice *port, u32_t pin, int flags);

there is no description on which flags are allowed, and what they mean. 

Looking further into the zephyr docs, I found this: https://docs.zephyrproject.org/latest/reference/peripherals/gpio.html

but values here is not accepted by the compiler. Rightclicking on other legal flag values doesn't lead me to definitions either in segger. I now have 2 questions: 

1. Where are the values described?
2. Why is standard Zephyr values not accepted, since the nrf9160 should run on Zephyr?

I'm running on mfw-1.1.0.

Hi.

 

but values here is not accepted by the compiler.

 What flags did you try, what errors did you get, and what configurations did you have in your project?

Best regards,

as an example, when I add the line

   gpio_pin_configure(gpio_dev, 29, GPIO_OUTPUT_INACTIVE);

I'm getting the compile error

../src/gpio.c:108:38: error: 'GPIO_OUTPUT_INACTIVE' undeclared (first use in this function); did you mean 'GPIO_OUTSET_PIN2_Set'?

And Yes,

#include <drivers/gpio.h>

is present

And 

CONFIG_GPIO=y

Is present in my prj.conf

Could you try the flags described in this file: https://github.com/NordicPlayground/fw-nrfconnect-zephyr/blob/master/include/dt-bindings/gpio/gpio.h ?
