Add driver and documentation for mp2888 device from Monolithic Power
Systems, Inc. (MPS) vendor. This is a digital, multi-phase, pulse-width
modulation controller.

Patch set includes:
Patch #1 - increases maximum number of phases.
Patch #2 - provides mp2888 driver and documentation.
Patch #3 - providesy binding documentation.

Vadim Pasternak (3):
  hwmon: (pmbus) Increase maximum number of phases per page
  hwmon: (pmbus) Add support for MPS Multi-phase mp2888 controller
  dt-bindings: Add MP2888 voltage regulator device

Thank you, Guenter.

I see from the following errors from robot:
>> ERROR: modpost: module mp2888 uses symbol pmbus_do_probe from namespace PMBUS, but does not import it.
>> ERROR: modpost: module mp2888 uses symbol pmbus_read_word_data from namespace PMBUS, but does not import it.
>> ERROR: modpost: module mp2888 uses symbol pmbus_write_word_data from namespace PMBUS, but does not import it.
>> ERROR: modpost: module mp2888 uses symbol pmbus_get_driver_info from namespace PMBUS, but does not import it.

What does it mean?

It needs

MODULE_IMPORT_NS(PMBUS);

No worries, I'll fix it up.
