Subject: PM / OPP: Rename OPP nodes as opp@<opp-hz>
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=754dcf35f34698661801ae1d391efa02affe83a7;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

PM / OPP: Rename OPP nodes as opp@<opp-hz>

It would be better to name OPP nodes as opp@<opp-hz> as that will ensure
that multiple DT nodes don't contain the same frequency. Of course we
expect the writer to name the node with its opp-hz frequency and not any
other frequency.

And that will let the compile error out if multiple nodes are using the
same opp-hz frequency.
