    Subject[RFT PATCH v2 08/14] arm64: dts: qcom: sc7180: switch TCSR mutex to MMIO
    Date
    The TCSR mutex bindings allow device to be described only with address
    space (so it uses MMIO, not syscon regmap). This seems reasonable as
    TCSR mutex is actually a dedicated IO address space and it also fixes DT
    schema checks:

    qcom/sc7180-trogdor-wormdingler-rev1-inx.dtb: hwlock: 'reg' is a required property
    qcom/sc7180-trogdor-wormdingler-rev1-inx.dtb: hwlock: 'syscon' does not match any of the regexes: 'pinctrl-[0-9]+'
