2013-01-26hwmon: Replace SENSORS_LIMIT with clamp_valGuenter Roeck1-3/+3
SENSORS_LIMIT and the generic clamp_val have the same functionality, and clamp_val is more efficient. This patch reduces text size by 9052 bytes and bss size by 11624 bytes for x86_64 builds.

2012-07-28hwmon: (jc42) Don't reset hysteresis on device removalJean Delvare1-3/+10
Restoring the configuration register on device removal has the side effect of also resetting the hysteresis value. This is inconsistent as the other limits are not reset, only hysteresis. So, following the principle of least surprise, preserve the hysteresis value when restoring the configuration register.

2012-07-28hwmon: (jc42) Simplify hysteresis maskJean Delvare1-7/+6
Define JC42_CFG_HYST_MASK as the mask _before_ shifting instead of after shifting. This simplifies the current code slightly, and will simplify the code to come even more.

My old e-mail address won't be valid for much longer. Time to update it. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Jean Delvare <khali@linux-fr.org>
2012-03-19hwmon: (jc42) Remove unnecessary device IDsGuenter Roeck1-18/+0
We don't really use or need separate device IDs for the various JC42.4 compliant chips, so remove them and just stick with jc42. Also update a datasheet references for SE98A, STTS424, and STTS424E02. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Jean Delvare <khali@linux-fr.org>
2012-03-19hwmon: (jc42) Convert to use devm_kzallocGuenter Roeck1-35/+25
Marginally less code and eliminate the possibility of memory leaks. Also replace new_client variable with client and introduce dev variable to make the code a bit easier to read. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2012-03-19hwmon: convert drivers/hwmon/* to use module_i2c_driver()Axel Lin1-12/+1
This patch converts the drivers in drivers/hwmon/* to use the module_i2c_driver() macro which makes the code smaller and a bit simpler.

2011-05-25hwmon: (jc42) Change detection classJean Delvare1-1/+1
While the JC42-compatible chips are temperature sensors, I2C_CLASS_SPD makes more sense because these chips always live on memory modules. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Guenter Roeck <guenter.roeck@ericsson.com>
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.
