20 * struct pinconf_ops - pin config operations, to be implemented by
21 * pin configuration capable drivers.
22 * @is_generic: for pin controllers that want to use the generic interface,
23 * this flag tells the framework that it's generic.
24 * @pin_config_get: get the config of a certain pin, if the requested config
25 * is not available on this controller this should return -ENOTSUPP
26 * and if it is available but disabled it should return -EINVAL
27 * @pin_config_set: configure an individual pin
28 * @pin_config_group_get: get configurations for an entire pin group; should
29 * return -ENOTSUPP and -EINVAL using the same rules as pin_config_get.
30 * @pin_config_group_set: configure all pins in a group
31 * @pin_config_dbg_show: optional debugfs display hook that will provide
32 * per-device info for a certain pin in debugfs
33 * @pin_config_group_dbg_show: optional debugfs display hook that will provide
34 * per-device info for a certain group in debugfs
35 * @pin_config_config_dbg_show: optional debugfs display hook that will decode
36 * and display a driver's pin configuration parameter
