thermal/drivers: Remove redundant error messages on IRQ request failure

2026-08-07T15:27:28+00:00

Since commit 55b48e23f5c4 ("genirq/devres: Add error handling in devm_request_*_irq()"), devm_request_irq() and devm_request_threaded_irq() automatically log detailed error messages on failure. Remove the now-redundant driver-specific dev_err() and dev_err_probe() calls.

thermal/drivers/mediatek/lvts_thermal: Make reset optional for MT8196

2026-08-07T15:18:48+00:00

Depending on the SoC+Firmware combination, the LVTS hardware may be may be actively used by one or even multiple concurrent MCUs! In this case, resetting it may produce either a severe slowdown of the entire system, or even a thermal protection AP reset, as some MCU(s) may be reading a very high or very low temperature while the LVTS is being reset. On those, don't fail if no reset is found as that may be omitted on purpose, but still check if there's one, because some board(s) may be running on a different bootchain with reduced firmwares or using firmwares with reduced functionality. So, use devm_reset_control_get_optional_exclusive() instead, as the LVTS controller always had only one reset and retrieving that by index, specifically, always made little sense anyway.

thermal/drivers/mediatek/lvts: Support MSR offset for 16-bit calibration data

2026-01-20T19:41:49+00:00

On MT8196/MT6991, per-sensor calibration data read from eFuses is 16-bit. When the LVTS controller operates in 16-bit mode, a fixed offset must be added to MSR values during post-processing to obtain correct temperature readings. Introduce a new msr_offset field in lvts_data, program the respective register and apply the offset to the calibration data read from eFuses.

thermal/drivers/mediatek/lvts: Add support for ATP mode

2026-01-20T19:41:49+00:00

MT8196/MT6991 uses ATP (Abnormal Temperature Prevention) mode to detect abnormal temperature conditions, which involves reading temperature data from a dedicated set of registers separate from the ones used for immediate and filtered modes. Add support for ATP mode and its relative registers to ensure accurate temperature readings and proper thermal management on MT8196/MT6991 devices. While at it, convert mode defines to enum.

thermal/drivers/mediatek/lvts: Add lvts_temp_to_raw variant

2026-01-20T19:41:49+00:00

MT8196/MT6991 require a different version of lvts_temp_to_raw(), specifically the multiplicative inverse of the existing implementation. Introduce a variant of the function with inverted calculation logic to match this requirement. This ensures accurate raw value generation for temperature thresholds, avoiding spurious thermal interrupts or unintended hardware resets on MT8196/MT6991.
