Subject: [PATCH v5 00/11] hwmon: (w83627ehf) Add support for NCT6775F and NCT6776F

The following patch series adds support for NCT6775F and NCT6776F to the
w83627ehf driver. It also includes some cleanup and adds support for
the fourth temperature sensor on W83677HG-B.

No code changes since v4. Resubmitting and widening audience in the hope that
someone may find the time to review the changes prior to the next commit window.

v5:
- Update Kconfig to reference W83667HG, NCT6775F, and NCT6776F.

v4:
- Store rpm instead of raw fan speed readings
- For NCT6775F, increase fan divisor if the fan speed reads 0
  [ On NCT6775F, fan speed readings can return 0 instead of 0xff if the
    fan divisor value is too low ]
- Separate changes into more patches to simplify review

v3:
- Documentation: Remove references to datasheets which no longer exist
- Documentation: Add information about limits of SmartFan IV support.
- SmartFan III mode is not supported on NCT6776F, so remove related attributes
  and refuse to configure it.
- (additional patch) Improve support for chips with 16-bit fan count registers

v2:
- W83677HG-B does share the AUXTIN/VIN3 pin, so we can not skip this check.
- Cosmetic changes to fix a couple of checkpatch errors and to undo some
  unnecessary formatting changes in patch 5.
- Patch 1 introduced a bug in temp_to_reg which was fixed in a later patch.
  Modified code to not introduce the bug in the first place.
- Two dev_dbg messages were changed to dev_info for testing. Changed back
  to dev_dbg.

The patched driver can be downloaded as stand-alone driver from
