Hi Peng,

Thanks for your comments, see below.

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.

Thanks, it'll be fixed into the v3 serie.

best regards,
  Vincent
