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.

Changes in v2:
As Heiko comments on
- interrupt-name use the lower case.
- use the correct compatible "arm,mali-t860"
- remove the clock name, since the mali only have one input clock.
- foo@ will produce warnings when used without reg property.
- update the commit to explain the two passive trip points changed.
