No, it should stay keep the rk3288-pmu compatible. While the 4 powerdomains
for the cores are similar, the pmu in general is very much specific to the
rk3288.
Also, this renaming of the pmu compatible only is a workaround for the
underlying problem, that your tree is probably missing the early syscon
support and there falling back to mapping the node directly.
If you apply the patch
[PATCH v7] mfd: syscon: Decouple syscon interface from platform devices
to your tree, it will work as expected by really using the pmu reference from
patch3 - it did for me - making this patch unnecessary.
