Subject: [PATCH v3 0/4] hwmon: Driver for SMM665 Six-Channel Active DC Output Controller/Monitor

This patchset adds support for the monitoring features of the Summit
Microelectronics SMM665 Six-Channel Active DC Output Controller/Monitor.

------

v2 changes:
- Added (untested) support for SMM465, SMM764, and SMM766.
- Added vref module parameter to support non-default values of VREF_ADC.
- Added an explanation describing what the chip does with _min and _max limit
  values.
- Removed alarm sysfs files (since the chip does not report alarm status in a
  register, alarm detection was implemented by comparing limits with ADC readings,
  which can as well be done in userland).
- Replaced register enums with defines.
- Made limit variable names better readable.
- Removed retries from smm665_read_adc().
- Check error reply from i2c_smbus_read_byte_data() and only accept ENXIO
  when expecting NACK.
- Explained reason for byte swap after reading ADC registers in some more detail.
- Added debug messages to display the error reason when reading ADC registers
  failed.

v3 changes:
- Return error codes from smm665_read_adc().
- Abort after first error in smm665_update_device() and return error code.
- Return ADC read errors to user.
- Added inX_lcrit and inX_crit attributes for min/max critical voltages.
- Added tempX_lcrit attribute for critical low temperature.
- Updated sysfs-interface to document support for new attributes.
