[PATCH v4 18/19] arm64: dts: mediatek: mt8183-pumpkin: Override vgpu/vsram_gpu constraints

From: AngeloGioacchino Del Regno
Date: Wed Mar 01 2023 - 04:56:36 EST


Override the PMIC-default voltage constraints for VGPU and VSRAM_GPU
with the platform specific vmin/vmax for the highest possible SoC
binning.
