    Subject[PATCH AUTOSEL 5.14 032/252] net: ipa: fix IPA v4.11 interconnect data
    Date
    From: Alex Elder <elder@linaro.org>

    [ Upstream commit 0ac26271344478ff718329fa9d4ef81d4bcbc43b ]

    Currently three interconnects are defined for the Qualcomm SC7280
    SoC, but this was based on a misunderstanding. There should only be
    two interconnects defined: one between the IPA and system memory;
    and another between the AP and IPA config space. The bandwidths
    defined for the memory and config interconnects do not match what I
    understand to be proper values, so update these.
