Public bug reported: [Impact] The MediaTek SSPM control interface and power_wrap driver are needed to provide firmware-managed device power, clock and mode control. The MT8901 audio series depends on the client power-control API introduced by this prerequisite series.
[Fix] Add the SCMI mailbox transport to the SSPM microcontroller, the ACPI-driven power_wrap driver, and the public client power-control request API. Include the sysfs debug interfaces, DVFSRC setup, the AC_BESTPERF boot request, release of idle USB4 resources through SSPM, and the kernel configuration annotations. [Where problems could occur] Changes to mailbox communication and firmware power-control requests could affect dependent devices, clock and power transitions, or entry to and resume from deep sleep. The client API is also a dependency of the separate audio series.
