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. Add support for AYANEO models 2S, AIR 1S, Flip series, GEEK 1S, and KUN. Signed-off-by:

The documented compatible string is "st,stts751", not "stts751". Even if "stts751" was in use, there's no need to list "stts751" in the DT match table. The I2C core will strip any vendor prefix and match against the i2c_device_id table which has an "stts751" entry. Signed-off-by:

Some of the newer Microsoft Surface devices (such as the Surface Book 3 and Pro 9) have thermal sensors connected via the Surface Aggregator Module (the embedded controller on those devices). Add a basic driver to read out the temperature values of those sensors. The EC can have up to 16 thermal sensors connected via a single sub-device, each providing temperature readings and a label string.

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. Signed-off-by:

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. While at it, drop "lm92: Found National Semiconductor LM92 chip" detection noise. Reviewed-by:

Use of_property_present() to test for property presence rather than of_get_property(). This is part of a larger effort to remove callers of of_get_property() and similar functions. of_get_property() leaks the DT property data pointer which is a problem for dynamically allocated nodes which may be freed.

Bit 0, 5, and 6 in the status register are reserved and, if set, do not indicate an alarm. Bit 7 is the 'busy' bit and also does not indicate an alarm. Mask the non-alarm bits to avoid reporting them to userspace. Cc: Tzung-Bi Shih <tzungbi@kernel.org> Reviewed-by:

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 1ea3fd1e ("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. Document the discrepancy to avoid confusion caused by old versions of the datasheet. Cc: Tzung-Bi Shih <tzungbi@kernel.org> Reviewed-by:
