| 1944 | * to create its PCM instances. |
| 1945 | * The allocated codec->pcm_info should be released in codec->patch_ops.free |
| 1946 | * callback. |
| 1947 | * |
| 1948 | * At least, substreams, channels_min and channels_max must be filled for |
| 1949 | * each stream. substreams = 0 indicates that the stream doesn't exist. |
| 1950 | * When rates and/or formats are zero, the supported values are queried |
| 1951 | * from the given nid. The nid is used also by the default ops.prepare |
| 1952 | * and ops.cleanup callbacks. |
| 1953 | * |
| 1954 | * The driver needs to call ops.open in its open callback. Similarly, |
| 1955 | * ops.close is supposed to be called in the close callback. |
| 1956 | * ops.prepare should be called in the prepare or hw_params callback |
| 1957 | * with the proper parameters for set up. |
| 1958 | * ops.cleanup should be called in hw_free for clean up of streams. |
