Thanks.
From: Jia-Wei Chang <jia-wei.chang@mediatek.com> This series supports MT8186 and MT8195 Smart Voltage Scaling (SVS) hardware which used as optimization of opp voltage table for corresponding dvfs drivers. This series is based on Roger's series [1]. [1]: Message ID: 20220516004311.18358-1-roger.lu@mediatek.com Change since v2: - Reuse platform probe of MT8192 for MT8195. - Remove unnecessary svs bank parameters of MT8195. - Remove sw id check for MT8195 efuse parsing. Change since v1: - Add myself as a co-maintainer of mtk-svs.yaml. - Fix MT8186 error handling in platform probe. - Add dt-bindings and support for MT8195 platform.
