    Subject[PATCH 0/6] Refine USB interrupt vectors on Qualcomm platforms
    Date
    Qualcomm targets define the following interrupts for usb wakeup:
    {dp/dm}_hs_phy_irq, hs_phy_irq, pwr_event, ss_phy_irq.

    But QUSB2 Phy based targets have another interrupt which gets triggered
    in response to J/K states on dp/dm pads. Its functionality is replaced
    by dp/dm interrupts on Femto/m31/eusb2 phy based targets for wakeup
    purposes. Exceptions are some targets like SDM845/SDM670/SM6350 where
    dp/dm irq's are used although they are qusb2 phy targets.

    Currently in QUSB2 Phy based DT's, te qusb2_phy interrupt is named and
    used as "hs_phy_irq" when in fact it is a different interrupt (used by
    HW validation folks for debug purposes and not used on any downstream
    target qusb/non-qusb).

    On some non-QUSB2 targets (like sm8450/sm8550), the pwr_event IRQ was
    named as hs_phy_irq and actual pwr_event_irq was skipped.

    This series tries to address the discrepancies in the interrupt numbering
    adding the missing interrupts and correcting the existing ones.

    This series has been compared with downstream counter part and hw specifics
    to ensure the numbering is right. Since there is not functionality change
    the code has been only compile tested.

    However SC8280 is left unchanged. Its primary and secondary controllers
    also have hs_phy_irq but they are not added in this series because of
    one mismatch with hw specifics which needs to clarified. The control IRQ
    added and the interrupts added work fine today. Only the hs_phy_irq needs
    to be cleaned up which will be done later.
