The commit 90173a954a22 ("arm64: dts: qcom: msm8996: Add CPU opps")
added CPU OPP tables to msm8996.dtsi. However it went unnoticed that
MSM8996 and MSM8996Pro have significant differences in the supported
CPU frequencies. Moreover, differences between various speed bins were
also not handled in the DT. Fix all these issues by splitting msm8996pro
and fixing different opp-supported-hw.
Unlike previous attempts by Yassine Oudjana [1] [2], this patchset
doesn't require changing the cpufreq driver, keeping compatibility with
existing kernels (and thus easing backporting to stable kernels).
Yassine's patches were changed to keep compatibility.
While we are at it, also apply fixes to GPU OPP tables to acount for
small differences in supported frequencies.

Gracious ping. It would be nice to get CPU OPP tables sorted out.
