JSD-001 motherboard
All the components listed are controlled by Syscon and connected to it by a pin/trace either directlly or indirectlly, the traces are hidden in internal layers of the motherboard
By looking at the first syscon model used by the PS3 CXR713120-201GB where we know the names of the pin signals it seems these syscon control lines for voltage regulators could be the syscon pins named SW_xx_xx (switches, used as a generic name)
