I2C creates some sysfs nodes in the wrong places: not as children of parent
controllers, but as their peers (!). This puts them into the right place
always, instead of just when the adapter is on the platform bus.

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.

i2c-i801: Merge setup function
Merge i801_setup into i801_probe, as it doesn't make much sense to
have them split. This lets us handle errors better. Christopher
Hellwig had been suggesting this back in March 2003 when the driver
was merged.
Also drop two useless debug messages (revision and base address can be
obtained from lspci, procfs or sysfs.)

i2c-i801: Cleanups
Various cleanups to the i2c-i801 driver:
* Fix documentation file and self file name references.
* i801_setup can be marked __devinit.
* Drop useless error local variable and label in i801_setup.
* Avoid a double PCI configuration register write in some cases.
* Use symbolic names for SMBHSTCFG bits.
* Transmit the error code returned by i801_setup instead of forcing it
to an arbitrary value.

One of my testers had a problem where the driver only saw 2 of the 4 fan
sensors his uGuru has, this fixes this.
-accept 0x40 (bit 6) being high as a valid fan sensor setting for all fans
not just fan 1, I have a feeling this bit indicates whether or not a fan is
actually connected .

Fixes to the Abit uGuru driver as requested in review by Jean Delvare:
- exactly calculate the sysfs_names array length using macro
- use snprintf when generating names to double check that the sysfs_names
array does not overflow.
- use ARRAY_SIZE and / or defines to determine number of loops in for loops
instead of using hardcoded values.
- In abituguru_probe(), refactor the error path leaving a single call to kfree

W83792D use pwm register low 4 bits to store PWM/DC value, bit 7
is used to store fan PWM/DC mode. The store_pwm function did not
convert the pwm input correctly, so it may change the fan mode
when new value is set.
This fix the problem. Change the "index" value of pwm*_mode
and pwm* SENSOR_ATTR to simplify code.

This patch removes the fix_hstcfg option from the driver and related
SMBus Interrupt Select register magic because now we know what are
valid values for this register. This patch updates the documentation
and adds new IRQ mode check so we are sure not to miss any new
"unusual" value.
The PCI quirk for users of fix_hstcfg was not developed because the
chipset lacks of subsystem ID registers and DMI is stated "To be
filled". Impact to existing systems is minimal because the problem
showed up on motherboards like 10 years back. On the other hand users
of newer Serverworks and HT1000 systems won't be misleaded by the
message suggesting to try the fix_hstcfg any more.

This patch adds support for the ST m41t81 and m41t85 i2c rtc chips
to the existing m41t00 driver.
Since there is no way to reliably determine what type of rtc chip
is in use, the chip type is passed in via platform_data. The i2c
address and square wave frequency are passed in via platform_data
as well. To accommodate the use of platform_data, a new header
file include/linux/m41t00.h has been added.
The m41t81 and m41t85 chips halt the updating of their time registers
while they are being accessed. They resume when a stop condition
exists on the i2c bus or when non-time related regs are accessed.
To make the best use of that facility and to make more efficient
use of the i2c bus, this patch replaces multiple i2c_smbus_xxx calls
with a single i2c_transfer call.

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.
