nrfx ADC HAL / Driver Problem Zephyr

Question

Dear Nordic Community

I am trying to get the nrfx adc driver to work with zephyr (link). With the help of this post, I ended up with the following code:

prj.conf ->

CONFIG_ADC=n
CONFIG_NRFX_SAADC=y

main.c ->

#include <zephyr.h>
#include <nrfx_adc.h>

struct nrfx_adc_channel_s spec_ana_ch;

void adc_init(){
  //Setup ADC
  nrfx_adc_init(NRFX_ADC_DEFAULT_CONFIG,NULL);
  spec_ana_ch.config.resolution = NRF_ADC_CONFIG_RES_10BIT;
  spec_ana_ch.config.scaling = NRF_ADC_CONFIG_SCALING_INPUT_FULL_SCALE;
  spec_ana_ch.config.extref = NRF_ADC_CONFIG_EXTREFSEL_NONE;
  spec_ana_ch.config.reference = NRF_ADC_CONFIG_REF_SUPPLY_ONE_HALF;
  spec_ana_ch.config.input = SPEC_ANA_CH;
  nrfx_adc_channel_enable(&spec_ana_ch);
}

/**@brief Function for application main entry.
 */
void main(void) {

  // Init Board
  adc_init();
}

but compiling fails with the following croped error message:

I did some research and found out that the missing declaration of ADC_CONFIG_RES_8bit should happen in the soc-specific bitfields header file, as defined in nrf51_bitfields.h.

But this file only gets included when there is a nRF51 SOC used. So is the file nrf_adc.h is not usabel with newer SOCs than nRF51?

Thanks for your help in advance.

My enviroment is:
