2012-03-19hwmon: (jc42) Remove unnecessary device IDsGuenter Roeck
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>
2012-03-07hwmon: (jc42) Add support for AT30TS00, TS3000GB2, TSE2002GB2, and MCP9804Guenter Roeck
Also update IDT datasheet locations. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Cc: stable@vger.kernel.org # 3.0+ Acked-by: Jean Delvare <khali@linux-fr.org>
2012-03-07hwmon: (jc42) Add support for ST Microelectronics STTS2002 and STTS3000Jean Delvare
These are fully compatible with Jedec JC 42.4 as far as I can see. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Guenter Roeck <guenter.roeck@ericsson.com> Cc: stable@vger.kernel.org # 3.0+ Signed-off-by: Guenter Roeck <guenter.roeck@ericsson.com>
2011-02-16hwmon: (jc42) do not allow writing to locked registersClemens Ladisch
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.

2011-02-16hwmon: (jc42) more helpful documentationClemens Ladisch
The documentation lists standard numbers and chip names in excruciating detail, but that's all it does. To help mere mortals in deciding whether to enable this driver, mention what this sensor is for and in which systems it might be found. Also add a link to the actual JC 42.4 specification.
