c06e677aed SPI: add 3wire mode flag
Add a new spi->mode bit: SPI_3WIRE, for chips where the SI and SO signals
are shared (and which are thus only half duplex).  Update the LM70 driver
to require support for that hardware mode from the controller.

8bb7844286 Add suspend-related notifications for CPU hotplug
Since nonboot CPUs are now disabled after tasks and devices have been
frozen and the CPU hotplug infrastructure is used for this purpose, we need
special CPU hotplug notifications that will help the CPU-hotplug-aware
subsystems distinguish normal CPU hotplug events from CPU hotplug events
related to a system-wide suspend or resume operation in progress.  This
patch introduces such notifications and causes them to be used during
suspend and resume transitions.  It also changes all of the
CPU-hotplug-aware subsystems to take these notifications into consideration
(for now they are handled in the same way as the corresponding "normal"
ones).

8a665a0552 hwmon: Only call vid_which_vrm() when needed
Some hardware monitoring drivers create the VID/VRM interface files
conditionally depending on the chip model or configuration. We should
only call vid_which_vrm() when we are actually going to create the
files. Not only it is more logical and efficient that way, but it also
prevents printing unnecessary warnings such as the one reported here:

ce7ee4e80a hwmon: Request the I/O regions in platform drivers
My understanding of the resource management in the Linux 2.6 device
driver model is that the devices should declare their resources, and
then when a driver attaches to a device, it should request the
resources it will be using, so as to mark them busy. This is how the
PCI and PNP subsystems work, you can clearly see the two levels of
resources (declaration and request) in /proc/ioports for these
devices.

So I believe that our platform hardware monitoring drivers should
follow the same logic. At the moment, we only declare the resources
but we do not request them. This patch adds the I/O region request
and release calls.

33725ad36d hwmon/w83627ehf: Fix the fan5 clock divider write
Users have been complaining about the w83627ehf driver flooding their logs
with debug messages like:

w83627ehf 9191-0a10: Increasing fan 4 clock divider from 64 to 128

or:

w83627ehf 9191-0290: Increasing fan 4 clock divider from 4 to 8

The reason is that we failed to actually write the LSB of the encoded clock
divider value for that fan, causing the next read to report the same old value
again and again.

Additionally, the fan number was improperly reported, making the bug harder to
find.

a117dddf6b hwmon/f71805f: Fix a race condition
I think I introduced a potential race condition bug with commit
51c997d80e. I didn't realize it
back then, but platform_device_put and platform_device_release
both appear to free the platform data associated with the device.
This makes an explicit kfree redundant at best, and maybe even
racy, as it might occur while someone still holds a reference
to the platform device.

37f54ee546 hwmon: Use subsys_initcall
Subsystem infrastructure should normally register with "subsys_initcall",
so that it's available to drivers that may need to initialize early.

This patch updates "hwmon" to do so.  It's common for embedded systems to
have multifunction chips with hardware monitoring interfaces, and to have
those chips be used during system bringup ... before a normal "module_init"
would kick, or maybe just linked so they'd init before hwmon.

7f999aa726 hwmon: Simplify the locking model of two drivers
Many hardware monitoring drivers use two different mutexes, one to
protect their per-device data structure, and one to protect the
access to the device registers. These mutexes are essentially
redundant, as the drivers are transfering values between the device
registers and the data cache, so they almost always end up holding
both mutexes at the same time. Using a single mutex will make the
code more simple and faster.

I am changing only two of the affected drivers here, the authors
of the other affected drivers are welcome to submit similar patches
if they want.

Add support for the Fintek F71872F/FG Super-I/O chip. It is basically the
same as the Fintek F71805F/FG as far as hardware monitoring is concerned,
with two additional internal voltages monitored (VSB and battery), and 6
VID inputs (not yet supported.)

To make things a bit more confusing, two of the voltage input pins (in4
and in8) can be used for other functions. The driver reads the pin
configuration from the Super-I/O configuration space to decide whether
it must create interface files for these inputs or not.

code and reporting bugs.

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.

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.

faf9b61632 [PATCH] hwmon: abituguru timeout fixes
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.

e1a8e913f9 [PATCH] lm70: New hardware monitoring driver
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.
