arm64: dts: rockchip: Add the thermal data found on RK3368
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.
