    Subject[PATCH v2 3/5] usb: typec: tcpci_rt1711h: Add rxdz_sel variable to struct rt1711h_chip_info
    Date
    The RT1715 needs 0.35V/0.75V rx threshold for rd/rp whereas it is 0.4V/0.7V
    for RT1711H. Add rxdz_sel variable to struct rt1711h_chip_info for
    handling this difference.

    v1->v2:
    * Swapped the rxdz_sel variable in struct rt1711h_chip_info to avoid
    holes.
