ba224e2c4f hwmon: New PC87427 hardware monitoring driver
This is a new hardware monitoring driver for the National Semiconductor
PC87427 Super-I/O chip. It only supports fan speed monitoring for now,
while the chip can do much more.

Thanks to Amir Habibi at Candelis for setting up a test system, and to
Michael Kress for testing several iterations of this driver.

8e9afcbbde hwmon/it87: Remove the SMBus interface support
This interface was useless as the LPC ISA-like interface is always
available, is faster, and is more reliable. This cuts the driver
size by some 20%.

This change is also required to later convert the it87 driver to a
platform driver, so that we can get rid of i2c-isa in a near future.

The SMSC LPC47M112 Super-I/O chip appears to be compatible with the
LPC47M10x and LPC47M13x as far as hardware monitoring is concerned.
The device ID is even the same, so it's really only a documentation

The alarm bits and the beep enable bits are in different positions in

87673dd735 it87: Add support for the IT8718F
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
it87 driver was pretty straightforward. The most significant difference
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.)

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.

400b48ecd9 [PATCH] hwmon: Add sysfs interface for individual alarm files
Extend the sysfs interface of hardware monitoring chips, by adding
individual alarm and beep files. Contrary to the old aggregated "alarms"
and "beeps" files, individual files constitute a standard way to access
the status information, making it finally possible to implement a
chip-independant hardware monitoring chip access library (once all
drivers have been added this new interface, that is.)

If future drivers need more individual files, the interface will be
extended as needed at the same time these drivers are merged into the
kernel tree.

c5e3fbf22c [PATCH] hwmon: Fix reboot on it87 driver load
Only scan I2C address 0x2d. This is the default address and no IT87xxF
chip was ever seen on I2C at a different address. These chips are
better accessed through their ISA interface anyway.

This fixes bug #5889, although it doesn't address the whole class
of problems. We'd need the ability to blacklist arbitrary I2C addresses
on systems known to contain I2C devices which behave badly when probed.

Plan the I2C interface for removal as well. If nobody complains within
a year, it will confirm my impression that the I2C interface isn't
actually needed by anyone.

This is my f71805f hardware monitoring driver ported from lm_sensors
to Linux 2.6. This new driver differs from the other hardware monitoring
drivers in that it is implemented as a platform driver. This might not
be optimal yet (we would probably need a generic infrastructure and bus
type for Super-I/O logical devices) but it is certainly much better than
the i2c-isa solution.

Note that this driver requires lm_sensors CVS. I hope to get it

As enabling PEC causes a significant performance drop, it can be
disabled through a sysfs file (unsurprisingly named "pec").

only a later revision of the LM78, with almost no difference and
no difference the driver handles in any case.

This was the only client name that had a dash in it, and special care
had to be taken in libsensors because of it. As we plan to write a new
library soon, I'd like to get rid of this exception before we do.

As a nice side effect, it saves 876 bytes in lm78.ko.
