hwmon: (it87) Prevent power-off on Shuttle SN68PT

2008-10-22T21:13:27+00:00

based on commit 98dd22c3e086d76058083432d4d8fb85f04bab90 upstream

On the Shuttle SN68PT, FAN_CTL2 is apparently not connected to a fan,
but to something else. One user has reported instant system power-off
when changing the PWM2 duty cycle, so we disable it.

I use the board name string as the trigger in case the same board is
ever used in other systems.

This closes lm-sensors ticket #2349:
pwmconfig causes a hard poweroff

hdaps: add support for various newer Lenovo thinkpads

2008-07-04T17:40:06+00:00

Adds R61, T61p, X61s, X61, Z61m, Z61p models to whitelist.

Fixes this:

cullen@lenny:~$ sudo modprobe hdaps
FATAL: Error inserting hdaps (/lib/modules/2.6.22-10-generic/kernel/drivers/hwmon/hdaps.ko): No such device

[25192.888000] hdaps: supported laptop not found!
[25192.888000] hdaps: driver init failed (ret=-19)!

Originally based on an Ubuntu patch that got it wrong, the dmidecode
output of the corresponding laptops shows LENOVO as the manufacturer.

hwmon: (lm75) sensor reading bugfix

2008-06-19T10:50:32+00:00

LM75 sensor reading bugfix: never save error status as valid
sensor output.  This could be improved, but at least this
prevents certain rude failure modes.

hwmon: (abituguru3) update driver detection

2008-06-19T10:50:32+00:00

It has been reported that the abituguru3 driver fails to load after a BIOS
update. This patch fixes this by loosening the detection routine so that it
will work after the BIOS update too. To compensate for the now very loose
detection an additional check is added on the DMI Base Board vendor string to
make sure we only load on Abit motherboards, this is the same as the check in
the abituguru (1 / 2) driver.

hwmon: (adt7473) Initialize max_duty_at_overheat before use

2008-06-19T10:50:31+00:00

data->max_duty_at_overheat is not updated in adt7473_update_device,
so it might be used before it is initialized (if the user reads from
sysfs file max_duty_at_crit before writing to it.)

hwmon: (lm85) Fix function RANGE_TO_REG()

2008-06-19T10:50:31+00:00

Function RANGE_TO_REG() is broken. For a requested range of 2000 (2
degrees C), it will return an index value of 15, i.e. 80.0 degrees C,
instead of the expected index value of 0. All other values are handled
properly, just 2000 isn't.

The bug was introduced back in November 2004 by this patch:
http://git.kernel.org/?p=linux/kernel/git/tglx/history.git;a=commit;h=1c28d80f1992240373099d863e4996cdd5d646d0

While this can be fixed easily with the current code, I'd rather
rewrite the whole function in a way which is more obviously correct.
