This patchaddresses an issue reported by a Chromebook customer. When the GPU regulator is turned on, mediatek_regulator_balance_voltage already sets both the GPU and GPU_SRAM voltages at the same time, so there is no need to adjust the GPU_SRAM voltage again in a second round. Therefore, a return is set for MT8189. If the user calls mediatek_regulator_balance_voltage again for GPU_SRAM, it may cause abnormal behavior of GPU_SRAM. changes in v1: - mediatek-regulator-coupler mechanism for platform MT8189 Niklaus Liu (1): soc: mediatek: mtk-regulator-coupler: Add support for MT8189 drivers/soc/mediatek/mtk-regulator-coupler.c | 13 +++++++++++++ 1 file changed, 13 insertions(+) -- 2.46.0
