No, mulitiple MPS can be used and are supported, eaching having its own i2c/bus addresses/DT node. For instance, you'd need a MPS for the lx2160 and another MPS for an ASIC. What is somehow unique is the CLI concept of "active" chip: 'pmbus dev' selects one deviec for the following subcommands (telemetry, status, dump, etc...). In fact, it follows the same way than i2c dev or mmc dev that I get inspired from. > >Adaapted from Linux code. > > Typo. Thanks, it'll be fixed into the v3 serie. best regards, Vincent
