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_x or SW_x_x (switches, used as a generic name for slave components that only has 2 states) | 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_x or SW_x_x (switches, used as a generic name for slave components that only has 2 states) | ||
