Note: f71805f actually checked the status from device_create_file

It was also an opportunity to use sysfs_create/remove_group instead
of hand-made loops. This makes the changes much more important but
I think the result is worth it.

Use sysfs_create_group() for 2 sensor-types which are chip-model
invariant, i.e. all-or-nothing attribute groups.
Other 2 groups vary too much due to configuration, etc, so we keep the

hwmon: New driver for the VIA VT1211

This is a new driver for the VIA VT1211 Super-IO chip. It is a rewrite
of the existing vt1211 driver (by Mark D. Studebaker and Lars Ekman)
which has been around for a while but never made it into the main
kernel tree.

It is implemented as a platform driver and therefore requires
lm_sensors 2.10.1 to function properly.

it87: Add support for the IT8718F

The IT8718F is a Super-I/O chip with integrated hardware monitoring
functions. It is very similar to the IT8716F, so adding support to the

is that the IT8718F has up to 8 VID pins, instead of 6 for the older
chips.

For the IT8718F, the VID value can only be read from Super-I/O space.

Userspace support is already in lm_sensors SVN (to be soon released
as 2.10.1.)

This patch contains 2 sets of fixes for the abituguru:
 1) Much improved timeout handling, drasticly reducing the amount of
    timeout errors on some motherboards
 2) Fix the exit paths in the bank1 sensor type detect code to always
    restore the original settings even on an error. Without this our
    special test settings could remain seriously confusing the system
    BIOS's setup menu.

Both are very much related and are must haves, to avoid messing up the
uguru CMOS settings.

Detailed changes:
- Much improved timeout / wait for status handling. Many thanks to Sunil
  Kumar, for all his testing, ideas and patches! The code now first busy
  waits, polling the uguru for the expected status as this usually
  succeeds pretty quickly (within 90 reads). To avoid unnecessary CPU burn
  in timeout conditions, the amount of busy waiting has been halved from
  previous versions (120 tries instead of 250). This is not a problem,
  because this version goes to sleep after 120 attemps for 1 jiffy and
  then tries again, it does this sleep and try again 5 times before
  finally giving up. This (almost?) completly removes the timeout errors
  some people have seen regulary. Apparently some older uguru versions
  sometimes are distracted for a (relatively) long time. This solves this.
- These timeout errors not only occur in the sending address part of
  reading the uguru but also in the wait for read state, so errors in
  this state are now handled as retryable just like send address state
  errors and are only logged and reported to userspace if 3 executive
  tries fail.
- Fix a very nasty bug in the bank1 sensor type detection code, where it
  would not restore the original settings in any of the error paths!
- Since not successfully restoring the original settings can seriously
  confuse the system BIOS (hang when entering the relevant setup menu),
  we now try restoring them 3 times before giving up.

This driver implements support for the National Semiconductor LM70
temperature sensor.

The LM70 temperature sensor chip supports a single temperature sensor.
It communicates with a host processor (or microcontroller) via an
SPI/Microwire Bus interface.

Communication with the LM70 is simple: when the temperature is to be sensed,
the driver accesses the LM70 using SPI communication: 16 SCLK cycles
comprise the MOSI/MISO loop. At the end of the transfer, the 11-bit 2's
complement digital temperature (sent via the SIO line), is available in the
driver for interpretation. This driver makes use of the kernel's in-core
SPI support.
