From 60fc93b35935a88b1e31d853a0abacf0847d8de4 Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Sat, 26 Nov 2022 00:38:31 +0100 Subject: [PATCH] ipq806x: disable cache and fabric devfreq driver to improve stability It was tested that cache scaling currently cause instability problem. This is probably caused by a latent misconfiguration that cause the L2 cache to be sourced from the wrong source and runs at an unstable freq compared to the original QSDK fw. To improve stability while the problem is bisected, disable the devfreq drivers with minimal perf penality.
