As noted in the
power controllers and PS-side and PL-side INA226 power monitors via the U60 PCA9544A
bus switch. All PMBus controlled Maxim regulators are tied to the MAXIM_PMBUS, while the
INA226 power monitors are separated on to PS_PMBUS and PL_PMBUS.

Maxim PMBus controllers and INA226 power monitor op amps. Also refer to schematic
0381701.
The MPSoC core related power rail measurements (PL_PMBUS) and PS related power
measurements (PS_PMBUS) are accessible to the system controller and PL logic through
their respective I2C0 bus connections. These measurements are displayed in the system
controller menu selections. The Maxim controller PMBus is also accessible by the system
controller, which can also display the rail voltage measurement made by its sourcing Maxim
controller. User IP in the PL can access the same set of PMBus resident devices through the
logic I2C0 connections.
