    -- set sink power to normal operation state (D0) before DPCD read
    
    Changes in v3:
    -- push idle pattern at main link before timing generator off
    -- add timeout handles for both connect and disconnect
    
    Changes in v4:
    -- add ST_SUSPEND_PENDING to handles suspend/modeset test operations
    -- clear dp phy aux interrupt status when ERR_DPPHY_AUX error
    -- send segment addr during edid read
    -- clear bpp depth before MISC register write
    
    Changes in v5:
    -- add ST_SUSPENDED to fix crash at resume

    -- at msm_dp_display_enable() do not return until resume_done to avoid
       kms commit timeout
