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 v12: - Change reg_data[3][] to reg_data[SVSB_PHASE_NUM][] - Change MT8192 SVS GPU opp count from 16 to 14 for project requirment - Remove redundant "pd_req = false" in svs_mt8192_banks - Assign svsp->bank_num by ARRAY_SIZE(svs_mt81xx_banks) - Replace `,` with `;` in svs_get_svs_mt8192_platform_data() Roger Lu (7): [v13,1/7]: dt-bindings: soc: mediatek: add mtk svs dt-bindings [v13,2/7]: arm64: dts: mt8183: add svs device information [v13,3/7]: soc: mediatek: SVS: introduce MTK SVS engine [v13,4/7]: soc: mediatek: SVS: add debug commands [v13,5/7]: dt-bindings: soc: mediatek: add mt8192 svs dt-bindings [v13,6/7]: arm64: dts: mt8192: add svs device information [v13,7/7]: 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 | 2494 +++++++++++++++++ 6 files changed, 2646 insertions(+) create mode 100644 Documentation/devicetree/bindings/soc/mediatek/mtk-svs.yaml create mode 100644 drivers/soc/mediatek/mtk-svs.c
