I think it was just the case of both being merged at the same time, and the -cpu-opp.dtsi not being in the branch where I based the .dts on. Will test and fix it! Regarding the OPPs: If you look at the table in sun50i_h616_efuse_xlate()[1], and then compare this to those SID numbers collected in our wiki[2], you will see that the "bins" are actually the packages: All H616s we have seen use 0x5000 (that's the low 16 bits of the first SID register value), the H618s uses 0x2000, and presumably all H313s use 0x5c00, and so on. I think BSP code confirms that. So the H313 uses a separate set of OPPs already (set 4), which is indeed the worst of them all: is requires higher voltages, and only provides up to 1.3GHz. So I *think* we should be covered. But please test this and report back if you have any issues.

Ah, right, bummer, same with the TX1, which is a bit annoying, because having BT would make this a bit more useful. > I'll spin a V2 after a few days, Thanks!
