Hi Imre, I actually had some question there as well: On Tue, Sep 16, 2014 at 03:35:15PM +0300, Imre Deak wrote: > > @@ -7685,24 +7689,32 @@ EXPORT_SYMBOL_GPL(i915_get_cdclk_freq); > > BIT(POWER_DOMAIN_PORT_DDI_C_2_LANES) | \ > > BIT(POWER_DOMAIN_PORT_DDI_C_4_LANES) | \ > > BIT(POWER_DOMAIN_PORT_CRT) | \ > > + BIT(POWER_DOMAIN_AUX_A) | \ > > + BIT(POWER_DOMAIN_AUX_B) | \ > > + BIT(POWER_DOMAIN_AUX_C) | \ > > + BIT(POWER_DOMAIN_AUX_D) | \ > > BIT(POWER_DOMAIN_INIT)) That's the VLV_DPIO_CMN_BC_POWER_DOMAINS, shouldn't we move AUX_A out of this define? 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?
