G3D power domain in Exynos5420 SoC is supplied from PVDD_G3DS_1V0 and PVDD_G3D_1V0. Besides the main GPU MALI module it also contains the power domain control logic and clocks. Turning the power supplies off causes the power domain to fail to operate properly if GPU drivers are loaded as modules. GPU should use PVDD_G3D_1V0 supply mainly to control the DVFS.
