73 | * How to use SRC bypass mode for debugging | |

75 | * SRC has bypass mode, and it is useful for debugging. | |
76 | * In Gen2 case, | |
77 | * SRCm_MODE controls whether SRC is used or not | |
78 | * SSI_MODE0 controls whether SSIU which receives SRC data | |
79 | * is used or not. | |
80 | * Both SRCm_MODE/SSI_MODE0 settings are needed if you use SRC, | |
81 | * but SRC bypass mode needs SSI_MODE0 only. | |
