[PATCH v3 02/18] arm64: dts: mediatek: mt8183-kukui: Override vgpu/vsram_gpu constraints

From: AngeloGioacchino Del Regno
Date: Tue Feb 28 2023 - 05:48:03 EST


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