hwmon: (w83627ehf) Be more careful when changing VID input level

2008-01-09T17:14:03Z

Already in Linus' tree: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=58e6e78119da2bdade9f6f588155f0320072b76b Fix for: http://bugzilla.kernel.org/show_bug.cgi?id=9634 The VID input level change has been reported to cause trouble. Be more careful in this respect: * Only change the level on the W83627EHF/EHG. The W83627DHG is more complex in this respect. * Don't change the level if the VID pins are in output mode. * Only set the level to TTL if VRM 9.x is used.

hwmon/lm87: Disable VID when it should be

hwmon/lm87: Fix a division by zero

hwmon/w83627hf: Don't assume bank 0

2007-11-16T17:30:20Z

Already in Linus' tree: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=d58df9cd788e6fb4962e1c8d5ba7b8b95d639a44 The bank switching code assumes that the bank selector is set to 0 when the driver is loaded. This might not be the case. This is exactly the same bug as was fixed in the w83627ehf driver two months ago: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0956895aa6f8dc6a33210967252fd7787652537d In practice, this bug was causing the sensor thermal types to be improperly reported for my W83627THF the first time I was loading the w83627hf driver. From the driver history, I'd say that it has been broken since September 2005 (when we stopped resetting the chip by default at driver load.) Signed-off-by: Jean Delvare Signed-off-by: Mark M.

hwmon/w83627hf: Fix setting fan min right after driver load

2007-11-16T17:30:19Z

That's pretty much the same bug and same fix as for the w83627ehf driver last month. Signed-off-by: Jean Delvare Signed-off-by: Mark M. Hoffman Signed-off-by: Greg Kroah-Hartman

hwmon: End of I/O region off-by-one

2007-09-09T14:38:37Z

Fix an off-by-one error in the I/O region declaration of two hardware monitoring drivers (lm78 and w83781d.) We were requesting one extra port at the end of the region. Signed-off-by: Jean Delvare Signed-off-by: Mark M. Hoffman

hwmon: (smsc47m1) restore missing name attribute

2007-08-12T18:39:44Z

The smsc47m1 driver no longer creates the name attribute used by libsensors to identify chip types. It was lost during the conversion to a platform driver. I was fooled by the fact that we do have a group with all attributes, but only to delete them all at once. The group is not used to create the attributes, so we have to explicitly create the name attribute.

hwmon: (w83627ehf) don't assume bank 0

2007-08-12T18:38:31Z

Don't assume that the default bank is 0. For one thing, we don't even set it to 0 when the driver is loaded, so the initial state might be different. For another, something (say, the BIOS) might access the chip and leave with the bank set to something different, so assuming that the bank value is 0 is not safe.

hwmon: (w83627ehf) read fan_div values during probe

2007-08-12T18:37:19Z

This patch forces the driver to read the fan divider values during early init. Otherwise, a call to store_fan_min() could access uninitialized variables. Signed-off-by: Mark M. Hoffman Signed-off-by: Jean Delvare

hwmon: fix w83781d temp sensor type setting

2007-08-11T18:22:57Z

Commit 348753379a7704087603dad403603e825422fd9a introduced a regression that caused temp2 and temp3 sensor type settings to be written to temp1 instead. The result is that temp sensor readings could be way off. Signed-off-by: Mark M. Hoffman
