The Loongson-2K0300's thermal sensor is generally compatible with the existing Loongson-2K series, but it features several key differences: 1. It has an independent CPU ID register for reading chip version information. 2. The raw temperature output field has been extended from 8 bits to 11 bits. 3. The temperature calculation formula has been updated to incorporate a correction factor based on the version information. To ensure robustness on older hardware revisions, a fallback mechanism is included: if the calculated temperature falls outside the valid range (-55 TO 125), the driver falls back to a simpler calculation and prints a warning. The patches have been validated on the Loongson-2K0300 development board. Thanks.
