Hi Rob & Heiko, Do we have the chance to merge these patches? I'm try to bring up the display and run webgl for testing with my github on https://github.com/Caesar-github/rockchip/commits/gru/next-stable-chromeos I believe the Rocky@RK will post patches to support the other SoCs after. -Caesar 在 2017年07月17日 16:14, Caesar Wang 写道:
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.
