From fbec0a1f775aa03ebb86c16fa761e6f52bb299ea Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Fri, 28 Feb 2020 15:55:01 +0100 Subject: [PATCH] ARM: dts: exynos: Fix G3D power domain supply on Odroid XU3/XU4/HC1 boards G3D power domain in Exynos5422 SoC is supplied from VDD_G3D. Besides the main GPU MALI module it also contains the power domain control logic and clocks. Turning the VDD_G3D power supply off causes the power domain to fail to operate properly and breaks for example system suspend/resume. GPU should use VDD_G3D supply mainly to control the DVFS.
