Subject: [PATCH mvebu v3 00/10] Armada 37xx: Fix cpufreq changing base CPU speed to 800 MHz from 1000 MHz

Hello!

This is third version of patches for Armada 37xx cpufreq driver which
fix CPU scaling with 1 GHz base frequency.

The only change in this third version is modified patch 04/10 with fixes
for 1.2 GHz variant of Espressobin. Minimal CPU voltage in L1 load for
1.2 GHz variant was increased to 1.155V.

Patches are now rebased on top of the kernel version 5.11 with all
collected Acked-by/Tested-by lines and are available also in my git
tree in branch a3720-cpufreq-issues:

https://git.kernel.org/pub/scm/linux/kernel/git/pali/linux.git/log/?h=a3720-cpufreq-issues

If you have other Armada 3720 boards with 1.2 GHz CPU, including
Espressobin V7, let us know if it is working fine for you.
