-Subject: [PATCH v2] cpufreq: armada-37xx: forbid cpufreq for 1.2 GHz variant
|
|

-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.
