[PATCH v3 0/3] hwmon: (pmbus/ltc2978) Add regulator ops

Hi!

The LTC2978 driver supports a wide range of power regulator chips, but it
has limited functionality for using it in a dynamic regulator framework.
Since standard functions for setting and getting voltage are missing as
pmbus core operations this patchset adds it.

These patches have been tested on an ARTPEC-8 developer board with a group
of LTC2977 power regulators.

Kind regards
Mårten Lindahl

Changes in v2:
- Add pmbus core _pmbus_write_byte_data to check for driver specific callback
- Change pmbus_update_byte_data to use _pmbus_read/write_byte_data
- Change pmbus_regulator_is_enabled to use _pmbus_read_byte_data
- Export pmbus core functions enable/disable/is_enabled

Changes in v3:
- Split patch "hwmon: (pmbus/ltc2978) Use driver specific ops if they exist"
into two patches: (1) pmbus core, (2) ltc2978.
- Move ltc2978_regulator_get/set_voltage functions to pmbus core.

hwmon: (pmbus) Use driver specific ops if they exist
hwmon: (pmbus/ltc2978) Add chip specific write_byte_data
hwmon: (pmbus) Add get_voltage/set_voltage ops
