+ * Name: nrf52_gpiotaskset
+ *
+ * Description:
+ * Configure GPIO in TASK mode (to be controlled via tasks).
+ * Note that a pin can only be either in TASK or EVENT mode (set by
+ * nrf52_gpiosetevent with event set to true). Also, once set to TASK mode,
+ * pin control is only possible via tasks on the via nrf52_gpio_write and
+ * will automatically set the output mode.
+ * Finally, a given pin should only be assigned to a given channel.
+ *
+ * Input Parameters:
+ * - pinset: gpio pin configuration (only port + pin is important here)
+ * - channel: the GPIOTE channel used to control the given pin
+ * - output_high: set pin initially to output HIGH or LOW.
+ * - outcfg: configure pin behavior one OUT task is triggered
+ *
+ * Returned Value:
+ * Zero (OK) on success; a negated errno value on failure indicating the
+ * nature of the failure.
+ *

Review comment:
```suggestion
#ifdef CONFIG_NRF52_HAVE_PORT1
int port = 0;
#endif
```
Just what I noticed :)
