Subject: Re: [PATCH mvebu v2 00/10] Armada 37xx: Fix cpufreq changing base CPU speed to 800 MHz from 1000 MHz

These changes to patch 04/10 worked going 600 MHz <-> 1.2 GHz , _but_ only with:

++#define MIN_VOLT_MV_FOR_L1_1200MHZ 1213

During this latest testing I saw freezes with 1132 mV.

I've had no lockups with 1213 mV which I just used from the values for L1/L0 from OTP.

I only tested with those two values.
