Hello, I am using Armbian on a Nanopi Neo Allwinner h3.
I build Armbian with the Armbianbuild repository and noticed that the CPU Frequency in all builds (minimal/standard) (buster/focal) are between 480MHz and 1.37GHz, but the H3 Soc only supports up to 1.2GHz.
This problem also occurs on the finished builds which are there to download from the Armbian website. (Tried with Armbian Buster kernel 5.8.y and Armbian Bionic 5.8.y)

analyzing CPU 0:
driver: cpufreq-dt
CPUs which run at the same hardware frequency: 0 1 2 3
CPUs which need to have their frequency coordinated by software: 0 1 2 3
maximum transition latency: 244 us.
hardware limits: 480 MHz - 1.37 GHz
available frequency steps: 480 MHz, 648 MHz, 816 MHz, 960 MHz, 1.01 GHz, 1.10 GHz, 1.20 GHz, 1.30 GHz, 1.37 GHz
available cpufreq governors: conservative, userspace, powersave, ondemand, performance, schedutil
current policy: frequency should be within 480 MHz and 1.37 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 480 MHz (asserted by call to hardware).
cpufreq stats: 480 MHz:77.19%, 648 MHz:0.91%, 816 MHz:0.01%, 960 MHz:0.00%, 1.01 GHz:0.01%, 1.10 GHz:0.02%, 1.20 GHz:0.02%, 1.30 GHz:0.03%, 1.37 GHz:21.80% (421)
In the Armbianbuild documentation the default settings in H2+ and H3 for the NanoPi Neo are 240-912MHz.
Is there an option to set the CPU Frequency to this range or is it a bug in the newer releases since the Nanopi Neo is a older board?
