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.
