hwmon: (jc42) Add support for additional IDT temperature sensors

2015-03-09T16:59:35+00:00

TS3000GB0 has a new device ID (0x2913). Since IDT's datasheets suggest that the upper 8 bit of the device ID reflect the chip ID and the lower 8 bit reflect the version number, modify the code to accept all chips with ID 0x29xx. Also add support for TS3001 and TSE2004. Some of the datasheets for older chips are no longer available from the IDT web site, so replace explicit links in the documentation with a generic note.

hwmon: (jc42) Allow negative hysteresis temperatures

2015-01-26T05:24:00+00:00

The driver supports negative high and critical limits, it can return negative hysteresis values, so there is no good reason to not let the user write negative hysteresis values. Signed-off-by: Jean Delvare Cc: Guenter Roeck Signed-off-by: Guenter Roeck

hwmon: (jc42) Fix integer overflow when writing hysteresis value

2015-01-26T05:23:59+00:00

Subtracting an unsigned long from a signed value causes an overflow with large values. Use clamp_val() to reduce the number range prior to subtracting it from the temperature limit. Signed-off-by: Guenter Roeck Reviewed-by: Jean Delvare

hwmon: (jc42) Fix integer overflow

2015-01-26T05:23:59+00:00

Mixed use of long and int caused an integer overflow when writing large limits. Signed-off-by: Guenter Roeck Reviewed-by: Jean Delvare

hwmon: (jc42) Use sign_extend32 for sign extension

2015-01-26T05:23:59+00:00

Despite the name, sign_extend32 works just fine for 16 bit variables, so it is safe to use. Cc: Martin Kepplinger Reviewed-by: Jean Delvare Signed-off-by: Guenter Roeck

hwmon: (jc42) Add support for STTS2004 and AT30TSE004

2014-05-21T23:02:25+00:00

Also fix links to datasheets for other supported sensors from ST Microelectronics, and add links to several Atmel datasheets. Signed-off-by: Guenter Roeck
