Perhaps do this in general manner, see how GPIOLIB takes care of it:

$ git grep -n -A4 -w CONFIG_OF_GPIO -- drivers/gpio/gpiolib.c
drivers/gpio/gpiolib.c:1161:#ifdef CONFIG_OF_GPIO
drivers/gpio/gpiolib.c-1162-    /* If the gpiochip has an assigned OF
node this takes precedence */
drivers/gpio/gpiolib.c-1163-    if (chip->of_node)
drivers/gpio/gpiolib.c-1164-            gdev->dev.of_node = chip->of_node;
drivers/gpio/gpiolib.c-1165-#endif
...
