Can anyone please pick it ASAP, so that we can finally get GPU support on MediaTek SoCs (including lots of Chromebooks)? Many thanks! Angelo

Queued to drm-misc-next. Thanks, Boris
Changes in v5: - Changed minItems for power-domain-names in base schema as suggested by Rob Changes in v4: - Refactored power-domains and power-domain-names exclusions as suggested by Krzysztof - Small changes in MT8192 bindings addition Changes in v3: - Changed MT8186 bindings to declare only two power domains - Added a commit introducing MT8186 specific platform data to panfrost_drv Changes in v2: - Add power-domain-names commit from Chen-Yu to the series - Kept sram-supply in base schema, overridden for non-MediaTek - Added Reviewed-by tags from Steven Price to the driver commits (as released in reply to v1's cover letter - thanks!) 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.
