From e7f2429130fbf5eb83d4e8d0c1c426ebd16a6d9d Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Mon, 21 Oct 2024 22:05:36 +0800 Subject: [PATCH] arm64: dts: mediatek: mt8186-corsola: Fix GPU supply coupling max-spread commit 2f1aab0cb0661d533f008e4975325080351cdfc8 upstream. The GPU SRAM supply is supposed to be always at least 0.1V higher than the GPU supply. However when the DT was upstreamed, the spread was incorrectly set to 0.01V.
