    The CPU Complex (CCPLEX) Power Manager (Denver MCE, or DMCE) is an
    offload engine for BPMP to do voltage related sequencing and for
    hardware requests to be handled in a better latency than BPMP-firmware.
    
    There are two interfaces to the MCEs - Abstract Request Interface (ARI)
    and the traditional NVGINDEX/NVGDATA interface.
    
    MCE supports various commands which can be used by CPUs - ARM as well
    as Denver, for power management and reset functionality. Since the
    linux kernel is the master for all these scenarios, each MCE command
    can be issued by a corresponding SMC. These SMCs have been moved to
    SiP SMC space as they are specific to the Tegra186 SoC.
