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 calls 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 v19: - Rebase to kernel 5.14-rc1 - Remove "if (svsp->rst)" check in svs_suspend()/svs_resume() because reset_control_assert()/reset_control_deassert() already takes care of this error handling.
