Hi everyone, this series adds support for hardware-tracked thermal trip points for the device tree thermal framework and introduces a new Tegra124 thermal driver that uses them. Hardware-tracked trip points are trip points that do not need to be polled; the hardware gives an interrupt when the trip point is reached. The device tree thermal framework has not previously given the sensor driver any information about set trip points, so using these has been impossible. This series adds a new callback from of-thermal to the driver to allow telling the driver about trip points. The driver only needs to track two trip points, the framework ensures that the current temperature lies between those two. Behavior for drivers that do not include this callback is unchanged. The Tegra124 SOCTHERM thermal driver that is included exposes four thermal zones (the thermctl thermal zones) with hardware-tracked trip point support. While the hardware supports four tracked trip points, only one is used.
