-Subject: [PATCH v2] cpufreq: armada-37xx: forbid cpufreq for 1.2 GHz variant
-Date: Thu, 1 Jul 2021 00:56:01 +0200
-
-The 1.2 GHz variant of the Armada 3720 SOC is unstable with DVFS: when
-the SOC boots, the WTMI firmware sets clocks and AVS values that work
-correctly with 1.2 GHz CPU frequency, but random crashes occur once
-cpufreq driver starts scaling.
-
-We do not know currently what is the reason:
-- it may be that the voltage value for L0 for 1.2 GHz variant provided
- by the vendor in the OTP is simply incorrect when scaling is used,
-- it may be that some delay is needed somewhere,
-- it may be something else.
-
-The most sane solution now seems to be to simply forbid the cpufreq
-driver on 1.2 GHz variant.
-
-Signed-off-by: Marek Behún <kabel at kernel.org>
-Fixes: 92ce45fb875d ("cpufreq: Add DVFS support for Armada 37xx")
