    usb: dwc3: make HIRD threshold configurable · 460d098c
    Huang Rui authored
    HIRD threshold should be configurable by different platforms.
    
    From DesignWare databook:
    When HIRD_Threshold[4] is set to 1b1 and HIRD value is greater than or
    equal to the value in HIRD_Threshold[3:0], dwc3 asserts output signals
    utmi_l1_suspend_n to put PHY into Deep Low-Power mode in L1.
    
    When HIRD_Threshold[4] is set to 1b0 or the HIRD value is less than
    HIRD_Threshold[3:0], dwc3 asserts output signals utmi_sleep_n on L1.
