SVS driver uses OPP adjust event in [1] to update OPP table voltage part. 2. SVS driver gets thermal/GPU device by node [2][3] and CPU device by get_cpu_device(). After retrieving subsys device, SVS driver does device_link_add() to make sure probe/suspend callback priority. 3. SVS dts refers to reset controller [4] to help reset SVS HW. #mt8183 SVS related patches [1] https://patchwork.kernel.org/patch/11193513/ [2] https://patchwork.kernel.org/project/linux-mediatek/patch/20201013102358.22588-2-michael.kao@mediatek.com/ [3] https://patchwork.kernel.org/project/linux-mediatek/patch/20200306041345.259332-3-drinkcat@chromium.org/ #mt8192 SVS related patches [1] https://patchwork.kernel.org/patch/11193513/ [2] https://patchwork.kernel.org/project/linux-mediatek/patch/20201223074944.2061-1-michael.kao@mediatek.com/ [3] https://lore.kernel.org/patchwork/patch/1360551/ [4] https://patchwork.kernel.org/project/linux-mediatek/patch/20200817030324.5690-5-crystal.guo@mediatek.com/ changes since v10: - Fix typos and remove duplicate GENASK() - Use DIV_ROUND_UP instead of creating own math - Remove fake_efuse related codes and some type casting - Optimize svs_get_vops_v2() coding - Check "supplier links.status DL_DEV_DRIVER_BOUND" to make sure supplier is ready after doing device_link_add() Roger Lu (7): [v11,1/7]: dt-bindings: soc: mediatek: add mtk svs dt-bindings [v11,2/7]: arm64: dts: mt8183: add svs device information [v11,3/7]: soc: mediatek: SVS: introduce MTK SVS engine [v11,4/7]: soc: mediatek: SVS: add debug commands [v11,5/7]: dt-bindings: soc: mediatek: add mt8192 svs dt-bindings [v11,6/7]: arm64: dts: mt8192: add svs device information [v11,7/7]: soc: mediatek: SVS: add mt8192 SVS GPU driver .../bindings/soc/mediatek/mtk-svs.yaml | 89 + arch/arm64/boot/dts/mediatek/mt8183.dtsi | 18 + arch/arm64/boot/dts/mediatek/mt8192.dtsi | 34 + drivers/soc/mediatek/Kconfig | 10 + drivers/soc/mediatek/Makefile | 1 + drivers/soc/mediatek/mtk-svs.c | 2492 +++++++++++++++++ 6 files changed, 2644 insertions(+) create mode 100644 Documentation/devicetree/bindings/soc/mediatek/mtk-svs.yaml create mode 100644 drivers/soc/mediatek/mtk-svs.c
