This register controls the SoundWire link vendor specific control / optimization.
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 31 | 0h | RW | Idle Clock Gating Disable (ICGD) When cleared to '0', the clock sources into the IP will be gated when CPA = 0. When set to '1', the clock gating will be disabled even though CPA = 0. |
| 30 | 0h | RW | Dynamic Clock Gating Disable (DCGD) When cleared to '0', it allows more aggressive dynamic clock gating during the idle windows of IP operation (CPA = 1). When set to '1', the clock gating will be disabled when CPA = 1. |
| 29:27 | 0h | RW | Host Link Clock Select (MLCS) Select the host link clock source. |
| 26 | 0h | RW | Force Clock Gating (FCG) When set to '1', it ignores all the HW detect idle conditions and force the clock to be gated assuming it is idle. |
| 25:0 | 0h | RO | Reserved (Preserved) (RSVD25) SW must preserve the original value when writing. |
