816d8c6a25 hwmon: (it87) Support for 16-bit fan reading in it8705 >= rev 0x03
The it8705 chip supports 16-bit fan tachometers in revisions at least
>= 0x03 (Version G). This patch enables 16-bit fan readings on all
revisions >= 0x03 just like the it8712, it8716, and it8718 chips.

116d0486bd hwmon: (hwmon-vid) Add 6-bit vid codes for AMD NPT 0Fh cpus
AMD NPT 0Fh cpus use 6 bit VID codes. Successive codes with msb 0
describe 25mV decrements, while those with msb 1 describe 12.5mV
decrements. Existing hwmon-vid.c is correct only for codes with msb 0;
add support for the codes with msb 1.

2f8ea97a45 hwmon: (w83627hf) Drop reset module parameter
Drop the reset parameter of the w83627hf driver. It seems it wasn't
that useful. It was dropped from the Linux 2.4 version of this driver
back in July 2004.

The only users who have reported that they were still using this
parameter, needed it to switch the chip from automatic fan speed
control back to manual mode. Now that the driver creates pwmN_enable
sysfs files, users will be able to use these files instead, which is
way less agressive.

Clean up and simplify the device initialization function:
* Degrade error messages to warnings - what they really are.
* Stop warning about VxI mode, we don't really care.
* Drop comment about lack of limit initialization - that's the standard
  way, all hardware monitoring drivers do that.
* Only read the configuration register once.
* Only write back to the configuration register if needed.
* Don't attempt to clear the lock bit, it locks itself to 1.
* Move the function to before it's called, so that we no longer need to
  forware declare it.

7133e56f29 hwmon: (lm85) Don't write back cached values
In set_pwm_auto_pwm_minctl, we write cached register bits back to the
chip. This is a bad idea as we have no guarantee that the cache is
up-to-date. Better read a fresh register value from the chip, it's
safer and in fact it is also more simple.

9ebd3d822e hwmon: (lm75) add new-style driver binding
More LM75 updates:

 - Teach the LM75 driver to use new-style driver binding:

     * Create a second driver struct, using new-style driver binding
       methods cribbed from the legacy code.

     * Add a MODULE_DEVICE_TABLE (for "newER-style binding")

     * The legacy probe logic delegates its work to this new code.

     * The legacy driver now uses the name "lm75_legacy".

 - More careful initialization.  Chips are put into 9-bit mode so
   the current interconversion routines will never fail.

 - Save the original chip configuration, and restore it on exit.
   (Among other things, this normally turns off the mode where
   the chip is constantly sampling ... and thus saves power.)

So the new-style code should catch all chips that boards declare,
while the legacy code catches others.  This particular coexistence
strategy may need some work yet ... legacy modes might best be set
up explicitly by some tool not unlike "sensors-detect".  (Or else
completely eradicated...)

01a52397e9 hwmon: (lm75) cleanup/reorg
Minor cleanup and reorg of the lm75 code.

 - Kconfig provides a larger list of lm75-compatible chips

 - A top comment now says what the driver does (!) ... as in, just
   what sort of sensor is this??

 - Section comments now delineate the various sections of the driver:
   hwmon attributes, driver binding, register access, module glue.
   One driver binding function moved out of the attribute section,
   as did the driver struct itself.

 - Minor tweaks to legacy probe logic:  correct a comment, and
   remove a pointless variable.

 - Whitespace, linelength, and comment fixes.

This patch should include no functional changes.  It's preparation
for adding new-style (driver model) I2C driver binding.
