"anything using SMEM"? As in the drivers, or SoCs?
If the former, I don't see how exporting a function from within
socid and using it here would make it required for other drivers.
If the latter, we're talking non-qcom SoCs. SMEM has been with
us forever.
I'm planning to reuse this for Adreno speedbin matching. It's one
of those blocks that don't have a revision and/or bin reigster
within themselves.
