2024-10-21soc: mediatek: mediatek-regulator-coupler: Support mt8188Pablo Sun1-0/+1
The Mali GPU in mt8188 also requires coupled power supplies, that is, the "vsram" voltage should follow the "vgpu" voltage. Therefore add the compatible to enable this coupling behavior.

2023-01-30soc: mediatek: Introduce mediatek-regulator-coupler driverAngeloGioacchino Del Regno1-0/+159
This driver currently deals with GPU-SRAM regulator coupling, ensuring that the SRAM voltage is always between a specific range of distance to the GPU voltage, depending on the SoC, necessary in order to achieve system stability across the full range of supported GPU frequencies.
