From f1aa231c929025f7cedcc6754aba852afd0b7b99 Mon Sep 17 00:00:00 2001 From: Alexey Charkov Date: Thu, 9 Oct 2025 16:34:01 +0400 Subject: [PATCH] arm64: dts: rockchip: Remove non-functioning CPU OPPs from RK3576 commit 05b80cd1f37db042e074ecc7ee0d39869fed2f52 upstream. Drop the top-frequency OPPs from both the LITTLE and big CPU clusters on RK3576, as neither the opensource TF-A [1] nor the recent (after v1.08) binary BL31 images provided by Rockchip expose those. This fixes the problem [2] when the cpufreq governor tries to jump directly to the highest-frequency OPP, which results in a failed SCMI call leaving the system stuck at the previous OPP before the attempted change.
