Andrew Paprocki 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.

The it8712 chip supports 16-bit fan tachometers in revisions >= 0x07.
Revisions >= 0x08 dropped support for 8-bit fan divisor registers. The
patch enables 16-bit fan readings on all revisions >= 0x07 just like
the it8716 and it8718 chips.

Jean Delvare 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.

Add support for the SCH5027. The differences to the DME1737 are:

- In auto mode, PWM outputs stay on min value if temp goes below low threshold
  and can't be programmed to fully turn off
- Different voltage scaling
- No VID input

This patch adds support for the SMSC SCH3112, SCH3114, and SCH3116 Super-I/O

expection that some of the fan inputs and pmw outputs don't exist.

The hardware monitoring features of the SCH311x chips can only be accessed via
the ISA bus. The driver therefore registers as a platform driver, if such a
chip is detected.

Jean Delvare 7817a39e65 hwmon: Fault files naming convention
We have the following naming convention documented in
Documentation/hwmon/sysfs-interface for fault files:

in[0-*]_input_fault
fan[1-*]_input_fault
temp[1-*]_input_fault

Some drivers follow this convention (lm63, lm83, lm90, smsc47m192).
However some drivers omit the "input" part and create files named
fan1_fault (pc87427) or temp1_fault (dme1737). And the new "generic"
libsensors follows this second (non-standard) convention, so it fails
to report fault conditions for drivers which follow the standard.

We want a single naming scheme, and everyone seems to prefer the
shorter variant, so let's go for it.
