This series adds support for new MediaTek SoCs (MT8186/MT8192/MT8195) and improves MT8183 support: since the mtk-regulator-coupler driver was picked, it is now useless for Panfrost to look for, and manage, two regulators (GPU Vcore and GPU SRAM) on MediaTek; The aforementioned driver will take care of keeping the voltage relation (/constraints) of the two regulators on its own when a voltage change request is sent to the Vcore, solving the old time issue with not working DVFS on Panfrost+MediaTek (due to devfreq supporting only single regulator). In the specific case of MT8183, in order to not break the ABI, it was necessary to add a new compatible for enabling DVFS.
