* group selector @pins, and the size of the array in @num_pins
* @pin_dbg_show: optional debugfs display hook that will provide per-device
* info for a certain pin in debugfs
* @dt_node_to_map: parse a device tree "pin configuration node", and create
* mapping table entries for it. These are returned through the @map and
* @num_maps output parameters. This function is optional, and may be
* omitted for pinctrl drivers that do not support device tree.
* @dt_free_map: free mapping table entries created via @dt_node_to_map. The

* allocated members of the mapping table entries themselves. This
