- * of_mm_gpiochip_add_data - Add memory mapped GPIO chip (bank)
- * @np:		device node of the GPIO chip
- * @mm_gc:	pointer to the of_mm_gpio_chip allocated structure
- * @data:	driver data to store in the struct gpio_chip
- *
- * To use this function you should allocate and fill mm_gc with:
- *
- * 1) In the gpio_chip structure:
- *    - all the callbacks
- *    - of_gpio_n_cells
- *    - of_xlate callback (optional)
- *
- * 3) In the of_mm_gpio_chip structure:
- *    - save_regs callback (optional)
- *
- * If succeeded, this function will map bank's memory and will
- * do all necessary work for you. Then you'll able to use .regs
- * to manage GPIOs from the callbacks.
- *
- * Returns:
- * 0 on success, or negative errno on failure.
