2011-03-14hwmon: (lm85) Add support for EMC6D103SGuenter Roeck1-24/+51
EMC6D103S is similar to EMC6D103, only it does not support registers 62[5:7], 6D[0:7], and 6E[0:7]. Register respective sysfs attributes and update affected registers for all other chips only. Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com> Acked-by: Jean Delvare <khali@linux-fr.org>
2011-03-14hwmon: (lm85) Do not update hysteresis and temp_auto_off if auto_temp_min is ↵Guenter Roeck1-17/+0
changed So far, the driver updates temp_auto_hyst and temp_auto_off if temp_auto_min changes. This may cause problems if temp_auto_off was not configured before configuring temp_auto_min, because one of the variables used (off_desired) is not initialized in this case. To simplify the code, and for consistency with other drivers, no longer update the delta between "min" and "off" until the user sets the "off" value again.

2011-02-18hwmon: (lm85) extend to support EMC6D103 chipsJan Beulich2-3/+22
The interface is identical EMC6D102, so all that needs to be added are some definitions and their uses. Registers apparently missing in EMC6D103S/EMC6D103:A2 compared to EMC6D103:A0, EMC6D103:A1, and EMC6D102 (according to the data sheets), but used unconditionally in the driver: 62[5:7], 6D[0:7], and 6E[0:7]. For that reason, EMC6D103S chips don't get enabled for the time being.

2011-02-16hwmon: (jc42) do not allow writing to locked registersClemens Ladisch1-4/+29
On systems where the temperature sensor is actually used, the BIOS is likely to have locked the alarm registers. In that case, all writes through the corresponding sysfs files would be silently ignored. To prevent this, detect the locks and make the affected sysfs files read-only.

2011-01-12hwmon: (w83793) Drop useless mutexJean Delvare1-4/+1
This is the same case as fschmd, from which the code was copied as far as I can see. So the same clean-up applies: The WDIOC_GETSUPPORT ioctl only needs a mutex because it operates on a static variable. There is no good reason to keep this variable static, so let's just make it non-static and drop the now useless mutex altogether.

2011-01-12hwmon: (via686a) Initialize fan_div valuesJean Delvare1-3/+11
Functions set_fan_min() and set_fan_div() assume that the fan_div values have already been read from the register. The driver currently doesn't initialize them at load time, they are only set when function via686a_update_device() is called. This means that set_fan_min() and set_fan_div() misbehave if, for example, "sensors -s" is called before any monitoring application (e.g. "sensors") is has been run. Fix the problem by always initializing the fan_div values at device bind time.
