From 50e7592cb696b3767d2186b0d51bb37a2fddbb67 Mon Sep 17 00:00:00 2001 From: Hsin-Te Yuan Date: Fri, 13 Dec 2024 09:29:22 +0000 Subject: [PATCH] arm64: dts: mediatek: mt8188: Add GPU speed bin NVMEM cells On the MT8188, the chip is binned for different GPU voltages at the highest OPPs. The binning value is stored in the efuse. Add the NVMEM cell, and tie it to the GPU.
