@AGM1968 in the description you've stated this patch adds CPU scaling to:

allwinner h616 6.x.y kernels

However, your patch applies to 6.2.y kernels only. Is there any reason why you didn't add the appropriate entries to at least 6.1 kernel as well (which is the current version, while 6.2 is edge atm)?

[AGM1968]

Technically no reason, my interest is in edge, as that supersedes.

EDGE, we can merge
