    Subject[RFT PATCH v3 02/16] arm64: dts: qcom: msm8996: split TCSR halt regs out of mutex
    Date
    The TCSR halt regs are next to TCSR mutex (in one address block called
    TCSR_MUTEX), so before converting the TCSR mutex into device with
    address space, we need to split the halt regs to its own syscon device.
