Convert the f71805f driver to use arrays of attributes. This shrinks the
compiled module from 12.0 kB to 9.6 kB. We certainly should do the same
for as many hardware monitoring drivers as possible.
This, together with a nice chip design by Fintek, makes this driver
very small, both in terms of number of lines of code and memory
consumption.

Use the real-time status registers of the Winbond W83782D, W83783S and
W83627HF chips, instead of the interrupt status registers. Interrupts
cannot be trusted at least for voltage inputs, as they are two-times

driver was fixed in a similar way some times ago.

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
released as 2.10.0 soon.

Just about every i2c chip driver sets the I2C_DF_NOTIFY flag, so we
can simply make it the default and drop the flag. If any driver really
doesn't want to be notified when i2c adapters are added, that driver
can simply omit to set .attach_adapter. This approach is also more

This patch changes w83627hf and w83627ehf drivers to reserve only ports
0x295-0x296, instead of full 0x290-0x297 range. While some other
sensors chips respond to all addresses in 0x290-0x297 range, Winbond
chips respond to 0x295-0x296 only (this behavior is implied by
documentation, and matches behavior observed on real systems). This is
not problem alone, as no BIOS was found to put something at these unused
addresses, and sensors chip itself provides nothing there as well.
But in addition to only respond to these two addresses, also BIOS
vendors report in their ACPI-PnP structures that there is some resource
at I/O address 0x295 of length 2. And when later this hwmon driver
attempts to request region with base 0x290/length 8, it fails as one
request_region cannot span more than one device.
Due to this we have to ask only for region this hardware really
occupies, otherwise driver cannot be loaded on systems with ACPI-PnP
enabled.
