23 | * @is_generic: for pin controllers that want to use the generic interface, |

| ae6b4d85 LW |
25 | * @pin_config_get: get the config of a certain pin, if the requested config |
| 26 | * is not available on this controller this should return -ENOTSUPP | |
| 27 | * and if it is available but disabled it should return -EINVAL | |
| ae6b4d85 | 28 | * @pin_config_set: configure an individual pin |
| 63f3fb8d DA |
29 | * @pin_config_group_get: get configurations for an entire pin group; should |
| 30 | * return -ENOTSUPP and -EINVAL using the same rules as pin_config_get. | |
| ae6b4d85 LW |
31 | * @pin_config_group_set: configure all pins in a group |
| 32 | * @pin_config_dbg_show: optional debugfs display hook that will provide | |
| 33 | * per-device info for a certain pin in debugfs | |
| 34 | * @pin_config_group_dbg_show: optional debugfs display hook that will provide | |
| 35 | * per-device info for a certain group in debugfs | |

36 | * @pin_config_config_dbg_show: optional debugfs display hook that will decode |
