Hi Imre, I actually had some question there as well:

Where does the port A lanes/aux should be on VLV and CHV, I don't see a good fit nor where the POWER_DOMAIN_PORT_DDI_A_X_LANES is today > > #define VLV_DPIO_TX_B_LANES_01_POWER_DOMAINS ( \ > > BIT(POWER_DOMAIN_PORT_DDI_B_2_LANES) | \ > > BIT(POWER_DOMAIN_PORT_DDI_B_4_LANES) | \ > > + BIT(POWER_DOMAIN_AUX_B) | \ > > BIT(POWER_DOMAIN_INIT)) > > > > #define VLV_DPIO_TX_B_LANES_23_POWER_DOMAINS ( \ > > BIT(POWER_DOMAIN_PORT_DDI_B_4_LANES) | \ > > + BIT(POWER_DOMAIN_AUX_B) | \ > > BIT(POWER_DOMAIN_INIT)) Wouldn't it better to leave the AUX domain in the LANES_01 power domain, otherwise we'll power up the full 4 lanes for aux transactions?
