This driver implements CPU frequency scaling for Apple Silicon SoCs, including M1 (t8103), M1 Max/Pro/Ultra (t600x), and M2 (t8112). Each CPU cluster has its own register set, and frequency management is fully automated by the hardware; the driver only has to write one register. There is boost frequency support, but the hardware will only allow their use if only a subset of cores in a cluster are in non-deep-idle. Since we don't support deep idle yet, these frequencies are not achievable, but the driver supports them. They will remain disabled in the device tree until deep idle is implemented, to avoid confusing users. This driver does not yet implement the memory controller performance state tuning that usually accompanies higher CPU p-states. This will be done in a future patch.
