* hwmon: (lm75) Add STLM75 supportJagan Teki2018-12-161-0/+5
| | | | | | | | | | | | | The STLM75 is a high-precision digital CMOS temperature sensor IC with a sigma-delta temperature-to-digital converter. The configuration register mapping is similar to existing lm75 but the sample rate is 150ms(max). Tested on real hardware and verified temperature readings are correct.

* hwmon: (lm75) Add MAX31725/6 supportKun Yi2018-10-101-3/+3
| | | | | | | | | | | | | MAX31725/MAX31726 are local temperature sensors with +/- 0.5 degree Celsius accuracy and 16-bit (0.00390625 degrees Celsius) resolution. They have a register mapping and encoding compatible with the lm75 series drivers. Address scan and extended temperature range are not supported by this patch. Tested on real hardware and verified temperature readings are correct. Signed-off-by: Kun Yi <kunyi@google.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
* hwmon: (lm75) Add support for TMP75CBen Gardner2015-10-141-2/+3
| | | | | | | | | The TMP75C has a different control register layout and only supports 12-bit temperature samples (0.0625 deg C). The continuous sample rate is ~12 Hz. Signed-off-by: Ben Gardner <gardner.ben@gmail.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

* hwmon: (lm75) Tune resolution and sample time per chipJean Delvare2013-05-041-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Most LM75-compatible chips can either sample much faster or with a much better resolution than the original LM75 chip. So far the lm75 driver did not let the user take benefit of these improvements. Do it now. I decided to almost always configure the chip to use the best resolution possible, which also means the longest sample time. The only chips for which I didn't are the DS75, DS1775 and STDS75, because they are really too slow in 12-bit mode (1.2 to 1.5 second worst case) so I went for 11-bit mode as a more reasonable tradeoff. This choice is dictated by the fact that the hwmon subsystem is meant for system monitoring, it has never been supposed to be ultra-fast, and as a matter of fact we do cache the sampled values in almost all drivers. If anyone isn't pleased with these default settings, they can always introduce a platform data structure or DT support for the lm75. That being said, it seems nobody ever complained that the driver wouldn't refresh the value faster than every 1.5 second, and the change made it faster for all chips even in 12-bit mode, so I don't expect any complaint.

* hwmon: (lm75) Document why clones are not detectedJean Delvare2011-10-241-24/+34
| | | | | | | | | | Explain why clones of the LM75 are generally not detected by the driver, and why this isn't going to change. Also update the documentation to reflect the list of chip names currently supported by the driver.

* hwmon: (lm75) Add support for Analog Devices ADT75Michael Hennerich2011-10-241-0/+5
| | | | | | | | | | | | | Add datasheet reference and device ID for ADT75. The ADT75, like some other LM75 derivatives, needs to be instantiated using methods 1, 2, or 4.

* [PATCH] I2C: Move hwmon drivers (3/3)Jean Delvare2005-07-111-0/+65
Part 3: Move the drivers documentation, plus two general documentation files. Note that the patch "adds trailing whitespace", because it does move the files as-is, and some files happen to have trailing whitespace.
