Sure, consider that everything is with +/-5%.
Qsdk ships with these values but I will link a more secure source that
is from a very old qsdk source where march-msm was still used instead of
dt.
Here the source [1]. Confirmed by internal verification and also other
qsdk. At first view you might be scared by confusion but...
- _lite = ipq8062
- nothing = ipq8064
- tn_3 = ipq8065
and the psv are both in number and slow, nominal, fast and faster and
they all reflect efuse values.
There is on the left frequency and on the right voltage.
