Newer (SM8550+) SoCs don't seem to have a nice speedbin fuse anymore, but instead rely on a set of combinations of "feature code" (FC) and "product code" (PC) identifiers to match the bins. This series adds support for that. I suppose a qcom/for-soc immutable branch would be in order if we want to land this in the upcoming cycle. FWIW I preferred the fuses myself.. Patches 5 and 6 coooould be omitted, but I'd reaaally like them to land and soon at that. This would enable even more overdue and necessary cleanups/feature prepwork sooner than later. The dt patch can only be picked if the drm patches are there.
