Subject: [V3 PATCH 0/1] soc: mediatek: mtk-regulator-coupler: Add support for MT8189

changes in V3:
 - modify for comment[add the new entry by alphabetical order] 

changes in V2:
 - change title for patch
 - reply comment: This is a software regulator coupler mechanism, and the regulator-coupled-with
configuration has been added in the MT8189 device tree. 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
