Thermal drivers offer a generic mechanism for thermal management. Usually it's made up of one or more thermal zones and cooling devices. Each thermal zone contains its own temperature, trip points, and cooling devices. All platforms with ACPI or OFW thermal support can use this driver. Signed-off-by: GuEe-GUI <2991707448@qq.com>
