    Subject[PATCH v3 5/5] mmc: dw_mmc: Set timeout to max upon resume
    Date
    The TMOUT register is initted to 0xffffffff at probe time but isn't
    initted after suspend/resume. Add an init of this value.

    No problems were observed without this (it will also get initted in
    __dw_mci_start_request if there is data to send), but it makes the
    register dump before and after suspend clean.
