| 1645 | * When rates and/or formats are zero, the supported values are queried |
| 1646 | * from the given nid. The nid is used also by the default ops.prepare |
| 1647 | * and ops.cleanup callbacks. |
| 1648 | * |
| 1649 | * The driver needs to call ops.open in its open callback. Similarly, |
| 1650 | * ops.close is supposed to be called in the close callback. |
| 1651 | * ops.prepare should be called in the prepare or hw_params callback |
