46243f3ab4 hwmon: (pmbus) Support reading and writing of word registers in device specific code
Some PMBus devices use non-standard registers for some of the sensors and/or
limits. To support such devices, add code to support reading and writing of word
size registers in device specific code.

2bd05bf4d2 hwmon: (pmbus) Increase attribute name size
Some hwmon sysfs attributes have a length of 20 bytes (plus terminating 0).
I2C_NAME_SIZE is defined as 20 and thus can not be used to define the length
of hwmon sysfs attributes. Replace it with PMBUS_NAME_SIZE, set to 24.

1061d8518f hwmon: (pmbus) Add support for VID output voltage mode
In VID mode, output voltages are measured and reported as VID values, and
have to be converted to voltages using VID conversion tables or functions.
Support is added for VR11 only at this time.

This patch enables support for PMBus devices supporting VID VR11 based output
voltage selection such as NCP4200 and NCP4208.

9d2ecfb768 hwmon: (pmbus) Move PMBus drivers to drivers/hwmon/pmbus
Since the number of PMBus drivers is getting large, move them into
directory drivers/hwmon/pmbus to improve readability and scalability.
