As pointed out by Konrad during the review of SM8350 / SC8280XP patchset, Iris aka Venus description has several flows. It doesn't scale MMCX, the frequencies in the OPP table are wrong, etc. Let's correct the Iris/Venus enablement for SM8250 (unfortunately also stopping it from being overclocked). Signed-off-by: Dmitry Baryshkov <redacted>Do you want me to pick up patch2 for v7.0 - or what do you suggest at this point?
I'd prefer it if it is picked through the immutable tag/branch.
Kind regards Uffequoted
