This series patches supported the mail in devicetree and used the thermal IPA by default. Verified with kernel is based on Linus's master branch and Heiko's v4.14-armsoc-tmp/dts64 branch. ( The Linux version 4.12.0 for now). The most rockchip SoCs will be supported with IPA mode for thermal in later. --- History version: 1. The first version found on https://www.spinics.net/lists/arm-kernel/msg593118.html Tested on Kevin board with bringing up ChromeOS.
