Previously, the 1GHz variants were marked as a turbo,
because that variant has reduced thermal operating range.

Now that the thermal throttling is in place, it should be
safe to remove the turbo-mode from the 1GHz variants, because
the CPU will automatically slow if the thermal limit is reached.

V2:  The orignal patch had the wrong file added. Add the omap36xx.dtsi
 

hmm, I somehow expected that there is a revert of this thing going
through. But now, the turbo-mode is still missing  

tagging by turbo-mode means the OPP is *disabled* by default and
needs to be enabled actively.

and I understood the
revert is only in Nikolaus' trees.  

It is just a revert for the gta04a5 because I think it is the only board
which is affected (maybe it would need SmartReflex in operation to
fine tune the OPPs compared to the generic table). Therefore I have
a patch which adds turbo-mode to the gta04a5.dts

The 1Ghz mode was working for some
time but does not anymore. Is it just me or do others also have the
same problems?  

That would be interesting to know.
 

What version are you seeing the break?  It's working for me on 5.15.y branch

# cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_frequencies

I see this one: I remember there was also a discussion about proper
handling of that but I do not remember the final result:

    This reverts commit cf395f7ddb9ebc6b2d28d83b53d18aa4e7c19701.
    
    This patch is in conflict with 1GHz OPP.

    ARM: DTS: gta04a5: disable 1GHz OPP again because it is not reliable
    
    To enable on a running system:
    
    echo 1 >/sys/devices/system/cpu/cpufreq/boost
    
    The symptom can be spurious hangs and virtual paging error,
    kernel panics and strange things.

on top of 5.13-rcX in Nikolaus trees.
