[PATCH v2 2/2] arm64: dts: exynos850: Add GPU/Mali Bifrost node
From: Thomas Turner
Date: Thu Aug 20 2026 - 10:24:04 EST
This can provide basic GPU functionality for the Exynos850 platform.
Tested on the SM-A217F device. Does not provide support for temperature
throttling, DVFS, power domains, governor support, boosting and voltage
control. Once PMIC is properly implemented, support will hopefully
increase. However the panfrost driver probes, the Mali-G52 GPU
initializes and the core clock is set-up.
