4ef664b5bc abituguru3: prefer DMI probing to manual probing
Previously the driver was only using DMI to prevent smbus probing on
non-Abit motherboards.  However, since the manual probing method is
brittle and prone to failure on some Abit motherboards (esp.  the Abit
IP35 Pro) it is better to use DMI to also read the board name and then
decide whether or not to probe the bus.

At the moment, we do not have a list of valid DMI name strings to use
for existing and supported motherboards.  This patch only implements DMI
probing for the IP35 Pro.  For motherboards that can not yet use DMI
probing, a warning will be printed to the kernel log asking those users
to email me their dmidecode output.

The existing manual probing mechanism will be used if CONFIG_DMI is not
enabled, if DMI probing fails (for DMI-unsupported motherboards), or if
DMI probing fails and the "force" option is set (for DMI-supported
motherboards).  Ideally in the longer term this manual probing method
would be removed.

This patch should be safe to apply as it does not change the probing
behaviour for most of the supported motherboards, just the IP35 Pro,
which already has regressions filed against it in 2.6.26.

b3aeab0cdb hwmon: (abituguru3) update driver detection
It has been reported that the abituguru3 driver fails to load after a BIOS
update. This patch fixes this by loosening the detection routine so that it
will work after the BIOS update too. To compensate for the now very loose
detection an additional check is added on the DMI Base Board vendor string to
make sure we only load on Abit motherboards, this is the same as the check in
the abituguru (1 / 2) driver.

cb96b8ca11 hwmon: (abituguru3) Add AUX4 fan input for Abit IP35 Pro
Abit IP35 Pro has 6 fan connectors (CPU, SYS and AUX1-4), but the
entry for AUX4 was missing from the table.

dcbd9f68ae hwmon: (abituguru3) Identify ABit IP35 Pro as such
This patch changes the identification string for motherboards with an id of
0x001A from unknown to "Abit IP35 Pro". Thanks to James Scott who has an Abit
IP35 Pro.

9c2e14afb9 hwmon: fix Abit Uguru3 driver detection on some motherboards
This patch changes the driver to also detect uguru3's which hold 0x08 at DATA
initially, as has been reported here:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=220160

Also when an uguru3's holds 0x0014 in the ID register it will now report
"Abit AB9 Pro" as motherboard identification.

3faa1ffb4f hwmon: Add support for newer uGuru's
This patch adds a new driver for the hardware monitoring features of the
third revision of the Abit uGuru chip, found on recent Abit
motherboards. This is an entirely different beast then the first and
second revision (its again a winbond microcontroller, but the "protocol"
to talk to it and the bank addresses are very different.
