+ * @param node_id   The devicetree node identifier.
+ * @param init_fn   Name of the init function of the driver.
+ * @param pm        PM device resources reference (NULL if device does not use PM).
+ * @param data      Pointer to the device's private data.
+ * @param config    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       Provides an initial pointer to the API function struct
