Setting the DWC_ahsata.SATA_PxSCTL[3:0] DET bit field to 0x4 automatically puts the SATA_PHY_RX deserializer in offline mode. This software operation has no impact over the SATA_PHY_TX serializer.
The SATA controller transition to partial or slumber mode has no impact over the SATA_PHY_RX deserializer.
The SATA_PHY_TX.TX_CLK output clock is a free-running clock and cannot be gated, even when the transmitter is disabled by a SATA controller.
