2021-06-23hwmon: (scpi-hwmon) shows the negative temperature properlyRiwen Lu1-0/+9
[ Upstream commit 78d13552346289bad4a9bf8eabb5eec5e5a321a5 ] The scpi hwmon shows the sub-zero temperature in an unsigned integer, which would confuse the users when the machine works in low temperature environment. This shows the sub-zero temperature in an signed value and users can get it properly from sensors.

2021-05-26Revert "hwmon: (lm80) fix a missing check of bus read in lm80 probe"Greg Kroah-Hartman1-9/+2
commit 99ae3417672a6d4a3bf68d4fc43d7c6ca074d477 upstream. This reverts commit 9aa3aa15f4c2f74f47afd6c5db4b420fadf3f315. Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, it was determined that this commit is not needed at all so just revert it. Also, the call to lm80_init_client() was not properly handled, so if error handling is needed in the lm80_probe() function, then it should be done properly, not half-baked like the commit being reverted here did.

2021-04-06hwmon: (sbtsi) Add basic support for SB-TSI sensorsKun Yi3-0/+261
SB Temperature Sensor Interface (SB-TSI) is an SMBus compatible interface that reports AMD SoC's Ttcl (normalized temperature), and resembles a typical 8-pin remote temperature sensor's I2C interface to BMC. This commit adds basic support using this interface to read CPU temperature, and read/write high/low CPU temp thresholds. To instantiate this driver on an AMD CPU with SB-TSI support, the i2c bus number would be the bus connected from the board management controller (BMC) to the CPU. The i2c address is specified in Section 6.3.1 of the spec [1]: The SB-TSI address is normally 98h for socket 0 and 90h for socket 1, but it could vary based on hardware address select pins. [1]: https://www.amd.com/system/files/TechDocs/56255_OSRR.pdf Test status: tested reading temp1_input, and reading/writing temp1_max/min.
