Changes in v4:
- tab-align values in #defines
- ensure locking in set_pwm covers updating cached values
- populate the cached value for the config register in tc654_probe()

Changes in v3:
- typofix in documentation
- add missing value to tc654_pwm_map, re-generate based on datasheet.
- remove unnecessary hwmon_dev member from struct tc654_data
- bug fixes in set_fan_min() and show_pwm_mode()
- miscellaneous style fixes
 
Changes in v2:
- Add Documentation/hwmon/tc654
- Incorporate most of the review comments from Guenter. Additional error
  handling is added. Unused/unnecessary code is removed. I decided not
  to go down the regmap path yet. I may circle back to it when I look at
  using regmap in the adm9240 driver.

Expect a merge conflict with the IIO tree.
