From 02c625c5de6028cebb7a1ade5d6f532c6a535e0d Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sat, 11 Apr 2020 18:57:00 +0200 Subject: dt-bindings: gpu: mali-utgard: Add the #cooling-cells property The GPU can be one of the big heat sources on a SoC. Allow the "#cooling-cells" property to be specified for ARM Mali Utgard GPUs so the GPU clock speeds (and voltages) can be reduced to prevent a SoC from overheating.
