 * @pin_config_get: get the config of a certain pin, if the requested config
 *	is not available on this controller this should return -ENOTSUPP
 *	and if it is available but disabled it should return -EINVAL
 * @pin_config_set: configure an individual pin
 * @pin_config_group_get: get configurations for an entire pin group; should
 *	return -ENOTSUPP and -EINVAL using the same rules as pin_config_get.
 * @pin_config_group_set: configure all pins in a group
 * @pin_config_dbg_show: optional debugfs display hook that will provide
 *	per-device info for a certain pin in debugfs
 * @pin_config_group_dbg_show: optional debugfs display hook that will provide
 *	per-device info for a certain group in debugfs
 * @pin_config_config_dbg_show: optional debugfs display hook that will decode
