It provides the board thermistors, the battery cell voltages and the CPU fan speed, and drives the keyboard backlight. Its interrupt line is TLMM gpio66, falling edge, for which the file already carries a pin state. That state leaves the pin without a bias. gpio66 has no external pull and floats when the EC is not driving it, which shows up as a steady stream of spurious edges; the vendor ACPI tables describe the same pin as GpioInt(Edge, ActiveLow, Exclusive, PullUp). Enable the pull-up. The binding and the driver are under review separately [1]; this node is inert until they land.
