[PATCH 0/4] arm64: dts: rockchip: support mail and IPA thermal for rk3399
This series patches supported the mail in devicetree and used the thermal IPA by default. Verified with rk3399 kevin board on my github https://github.com/Caesar-github/rockchip/commits/gru/next-stable-chromeos The 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). --- Tested on Kevin board with bringing up ChromeOS.
