nRF5340 - DAC driver in Zephyr

[Gabriele]

Hi,

to develop a device driver in Zephyr for TI DAC80501, a 16-bit DAC, I2C interface,

I have to

1. add the dts child node under the i2c controller node

  $i2c1 {
       dac80501@48 {
           compatible = "ti,dac80501";
           reg = <0x48>;
       };
  };

2. find a devicetree binding corresponding to the node's compatible property
3. write the driver in zephyr/drivers/adc/

Could anybody help me following through 2. and 3.

Thank you
