From cff64dca56cbeedcb2c76b21fe758895724b754c Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Thu, 11 Dec 2025 03:27:45 +0200 Subject: [PATCH] arm64: dts: qcom: sdm630: fix gpu_speed_bin size [ Upstream commit e814796dfcae8905682ac3ac2dd57f512a9f6726 ] Historically sdm630.dtsi has used 1 byte length for the gpu_speed_bin cell, although it spans two bytes (offset 5, size 7 bits). It was being accepted by the kernel because before the commit 7a06ef751077 ("nvmem: core: fix bit offsets of more than one byte") the kernel didn't have length check. After this commit nvmem core rejects QFPROM on sdm630 / sdm660, making GPU and USB unusable on those platforms. Set the size of the gpu_speed_bin cell to 2 bytes, fixing the parsing error. While we are at it, update the length to 8 bits as pointed out by Alexey Minnekhanov.
