Hans de Goede 3cad402281 hwmon/f71882fg: Add support for f71889ed
Note that this patch also makes 2 changes to the code paths for the f71889fg
to keep the code unified between the 2 (for simplicities sake). Both of these
are harmless for then f71889fg:

1) The first change is to always set the FAN_PROG_SEL bit to 0. This influences
   accesses to some banked fan / pwm registers. On the f71889fg no registers
   which we use are banked. On the f71889ed however some more fan registers
   have been banked including one which we use, by making the FAN_PROG_SEL bit
   0, address 0x96 will point to the right register.
2) The second change is to see a FANx_TEMP_SEL value of 0 as pointing to
   a PECI / AMDSI value, and thus disable our pwm related sysfs attr.
   This is correct for the f71889ed and on the f71889fg 0 is a reserved
   value, so we should never see it and if we do, disabling the pwm related
   sysfs attr is a sane thing to do.

Jean Delvare 44c1bcd4bc hwmon: (it87) Add support for the IT8721F/IT8758E
Add support for the IT8721F/IT8758E. These new chips differ from the
older IT87xxF chips in the following ways:
* ADC LSB is 12 mV instead of 16 mV.
* PWM values are 8-bit instead of 7-bit.
There are other minor changes we don't have to care about in the
driver.

Another change is that we will handle internal voltage scaling in the
driver instead of delegating the work to user-space.

Ira W. Snyder 5950ec8d3e hwmon: (ltc4245) Expose all GPIO pins as analog voltages
Add support for exposing all GPIO pins as analog voltages. Though this is
not an ideal use of the chip, some hardware engineers may decide that the
LTC4245 meets their design requirements when studying the datasheet.

The GPIO pins are sampled in round-robin fashion, meaning that a slow
reader will see stale data. A userspace application can detect this,
because it will get -EAGAIN when reading from a sysfs file which contains
stale data.

Users can choose to use this feature on a per-chip basis by using either
platform data or the OF device tree (where applicable).

  - Has one temperature sensor less (doesn't have temp3)
  - Misses one voltage sensor (doesn't have V6, thus in6_input refers to

updating broken web addresses that are located in Documentation/*
Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
Now there are also some addresses pointing to .spec files some are located, but some(after searching
on the companies site)where still no where to be found. In this case I just changed the address
to the company site this way the users can contact the company and they can locate them for the users.
