hwmon: (max34440) Fix resetting temperature history

2012-02-24T16:06:15+00:00

Temperature history is reset by writing 0x8000 into the peak temperature
register, not 0xffff.

hwmon: (f75375s) Fix register write order when setting fans to full speed

2012-02-23T14:47:47+00:00

By hwmon sysfs interface convention, setting pwm_enable to zero sets a fan
to full speed.  In the f75375s driver, this need be done by enabling
manual fan control, plus duty mode for the F875387 chip, and then setting
the maximum duty cycle.  Fix a bug where the two necessary register writes
were swapped, effectively discarding the setting to full-speed.

hwmon: (ads1015) Fix file leak in probe function

2012-02-23T14:47:41+00:00

An error while creating sysfs attribute files in the driver's probe function
results in an error abort, but already created files are not removed. This patch
fixes the problem.

hwmon: (max6639) Fix PPR register initialization to set both channels

2012-02-21T22:30:45+00:00

Initialize PPR register for both channels, and set correct PPR register bits.
Also remove unnecessary variable initializations.

hwmon: (max6639) Fix FAN_FROM_REG calculation

2012-02-21T22:30:12+00:00

RPM calculation from tachometer value does not depend on PPR.
Also, do not report negative RPM values.

hwmon: (f75375s) Let f75375_update_device treat pwmX as a measured value

2012-02-09T19:21:49+00:00

Treat pwmX as a measured value, not as a (mostly static) limit value, so
that it is updated more frequently from the device register.

hwmon: (f75375s) Fix bit shifting in f75375_write16

In order to extract the high byte of the 16-bit word, shift the word to
the right, not to the left.

hwmon: (f75375s) Fix reading of wrong register when initializing the F75387

2012-02-09T04:47:33+00:00

Unlike the other chips supported by this driver, the F75387 stores the
pwm_mode in register F75375_REG_FAN_TIMER, not F75375_REG_CONFIG1.

hwmon: (f75375s) Fix automatic pwm mode setting for F75373 & F75375

2012-02-09T04:47:33+00:00

In order to enable temperature mode aka automatic mode for the F75373 and
F75375 chips, the two FANx_MODE bits in the fan configuration register
need be set to 01, not 10.
