    Subject[PATCH 5.10 202/717] arm64: dts: qcom: sdm845: Limit ipa iommu streams
    Date
    From: Bjorn Andersson <bjorn.andersson@linaro.org>

    [ Upstream commit 95e6f8467c83c4074a6f6b47bad00653549ff90a ]

    The Android and Windows firmware does not accept the use of 3 as a mask
    to cover the IPA streams. But with 0x721 being related to WiFi and 0x723
    being unsed the mapping can be reduced to just cover 0x720 and 0x722,
    which is accepted.
