2024-08-27hwmon: (oxp-sensors) Add support for multiple new devices.Derek J. Clark2-63/+290
Add support for the OrangePi NEO-01. It uses different registers for PWM manual mode, set PWM, and read fan speed than previous devices. Valid PWM input and duty cycle is 1-244, we scale this from 1-255 to maintain compatibility with the existing interface. Add OneXPlayer 2 series, OneXFly, and X1 series models. The 2/X1 series use new registers for turbo button takeover and read fan speed. X1 has an Intel variant so change the CPU detection at init to only check for the affected devices. While at it, adjust formatting of some constants and reorder all cases alphabetically for consistency. Rename OXP_OLD constants to OXP_MINI for disambiguation. Update code comments for clarity.

There is no need to actively disable a regulator that has not been enabled by the driver, which makes the call to cc2_disable() in the probe function meaningless, because the probe function never enables the device's dedicated regulator. Once the call to cc2_disable() is dropped, the error paths can directly return dev_err_probe() in all cases.

2024-08-27hwmon: (lm92) Improve auto-detection accuracyGuenter Roeck1-9/+17
Checking three configuration register bits and the manufacturer ID register to auto-detect LM92 is a bit vague. Repeat twice on replicated register addresses to improve detection accuracy. Check the manufacturer ID first and bail out immediately without reading the other register if there is a mismatch to reduce the number of i2c transfers needed in that case. Also explicitly test for an error from reading the configuration register to avoid potential situations where the returned error masked against 0xe0 is 0.

In the MAX6581 datasheet Revision 0 to 3, the local channel overtemperature status is reported in bit 6 of register 0x45, and the overtemperature status for remote channel 7 is reported in bit 7. In Revision 4 and later, the local channel overtemperature status is reported in bit 7, and the remote channel 7 overtemperature status is reported in bit 6. A real chip was found to match the functionality documented in Revision 4 and later. The code was fixed with commit 1ea3fd1eb986 ("hwmon: (max6697) Fix swapped temp{1,8} critical alarms"). At that time it looked like this was an original bug. It only turned out later that the problem was the result of incorrect information in the chip datasheet.
