Long story short: this driver never worked as expected on any platform because of various issues so in this series there are some changes that will break compatibility with older device trees (of which, only MT8183 ever had the SVS node), but those are acceptable because... it never really worked fine anyway, so there's no regression. This series was tested on MT8186, MT8192, MT8195 Chromebooks. Depends on MT8192 thermal node: https://lore.kernel.org/lkml/20231017190545.157282-5-bero@baylibre.com/ MT8186 and MT8195 SVS support: https://lore.kernel.org/all/20231011034307.24641-1-chun-jen.tseng@mediatek.com/ Note: one commit was omitted because I haven't got feedback yet on the thermal-zones devicetree consumers implementation at [1], but I still wanted to send this series to the lists to get feedback. Please keep in mind that the one omitted commit is supposed to go on top of this series anyway, and that an useful example of how the SVS node will look with the DT thermal zones is provided at [1].
