Mediatek MT8173 is an ARMv8 based quad-core (2*Cortex-A53 and 2*Cortex-A72) SoC with duall clusters. For each cluster, two voltage inputs, Vproc and Vsram are supplied by two regulators. For the big cluster, two regulators come from different PMICs. In this case, when scaling voltage inputs of the cluster, the voltages of two regulator inputs need to be controlled by software explicitly under the SoC specific limitation: 100mV < Vsram - Vproc < 200mV which is called 'voltage tracking' mechanism. And when scaling the frequency of cluster clock input, the input MUX need to be parented to another "intermediate" stable PLL first and reparented to the original PLL once the original PLL is stable at the target frequency. This patch implements those mechanisms to enable CPU DVFS support for Mediatek MT8173 SoC.
