To address low-resolution sampling in Lenovo EC firmware, a Rate-Limited Lag (RLLag) filter is implemented. The filter ensures a consistent physical curve regardless of userspace polling frequency. Hardware identification is performed via DMI-based quirk tables, which map specific ACPI object paths and register widths (8-bit vs 16-bit) deterministically.

hwmon: (it87) Add support for IT8689E 2026-03-31T02:45:06+00:00 Markus Hoffmann markus@thehoffs.at 2026-03-22T10:33:01+00:00 66b8eaf8def2d51dab49c4921b93f1bf1c7638dc Add support for the ITE IT8689E Super I/O chip. The IT8689E supports newer autopwm, 12mV ADC, 16-bit fans, six fans, six PWM channels, PWM frequency 2, six temperature inputs, AVCC3, temperature offset, and fan on/off control. Give it8689 its own GPIO configuration block in it87_find() rather than sharing the it8620/it8628 block. The shared block reads IT87_SIO_PINX2_REG and either marks IN3 as internal AVCC or skips IN9. Because it8689 declares FEAT_AVCC3, IN9 is already marked as always-internal before the GPIO block is reached; applying the PINX2 check would either create duplicate AVCC labels on IN3 and IN9 or incorrectly skip IN9. Also update Documentation/hwmon/it87.rst and drivers/hwmon/Kconfig to document the newly supported chip.
