[PATCH] ARM: dts: ux500: Add trips to battery thermal zones

Linus Walleij linus.walleij at linaro.org
Sun Oct 30 14:08:54 PDT 2022


Recent changes to the thermal framework has made the trip
points (trips) for thermal zones compulsory, which made
the Ux500 DTS files break validation and also stopped
probing because of similar changes to the code.

Fix this by adding an "outer bounding box": battery thermal
zones should not get warmer than 70 degress, then we will
shut down.
