+ * @param node_id The devicetree node identifier.
+ * @param init_fn Name of the init function of the driver.
+ * @param pm_device PM device resources reference
+ * (NULL if device does not use PM).
+ * @param data_ptr Pointer to the device's private data.
+ * @param cfg_ptr The address to the structure containing the
+ * configuration information for this instance of the driver.
+ * @param level The initialization level. See SYS_INIT() for
+ * details.
+ * @param api_ptr Provides an initial pointer to the API function struct
+ * used by the driver. Can be NULL.
