This patchset add the thermal for RK3368 dts, Since the two CPU clusters, with four CPU core for each cluster, one cluster is optimized for high-performance(big cluster) and the othe is optimized for low power(little cluster). This patch adds the second order for thermal throttle, and the critical temperature for thermal over-tempeature protection on Software.
