As the main CPU clock input, the SoC uses CLKID_CPU_CLK from the CPU clock controller, which can be inherited from the system PLL (syspll) or a fixed CPU clock. Currently, the stable operating points at all frequencies are set to 800mV. This value is obtained from the vendor setup of several A1 boards.

As the main CPU clock input, the SoC uses CLKID_CPU_CLK from the CPU clock controller, which can be inherited from the system PLL (syspll) or a fixed CPU clock. Currently, the stable operating points at all frequencies are set to 800mV. This value is obtained from the vendor setup of several A1 boards.
