2006-03-23[PATCH] hwmon: Use attribute arrays in f71805fJean Delvare
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.

2006-02-13[PATCH] w83781d: Use real-time status registersJean Delvare
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 triggers (as opposed to comparator mode, which we want.) The w83627hf driver was fixed in a similar way some times ago.

2006-02-06[PATCH] hwmon: Fix reboot on it87 driver loadJean Delvare
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.

2006-02-06[PATCH] hwmon: New f71805f driverJean Delvare
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. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

This patch adds the VIA CENTAUR CPUs to detection table. Table was updated to treat future Intel x86 CPUs as VRD10.

Now that i2c_add_driver() doesn't need the module owner to be set by hand, we can delete it from the drivers.

2006-01-05[PATCH] i2c: Drop i2c_driver.flags, 2 of 3Jean Delvare
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.

2005-10-28[PATCH] hwmon: Add PEC support to the lm90 driverJean Delvare
Add PEC support to the lm90 driver. Only the ADM1032 chip supports it, and in a rather tricky way, which is why this patch comes with documentation reinforcements. At least, this demonstrates that the new PEC support logic in i2c-core can properly deal with chips with partial PEC support. As enabling PEC causes a significant performance drop, it can be disabled through a sysfs file (unsurprisingly named "pec").

2005-10-28[PATCH] hwmon: Fix w83627ehf/hf vs PNPACPI conflict (bug #4014)Petr Vandrovec
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.
