Please add comments here, see alpine-v2.dtsi (or other dtsi in
arch/arm64).

Looking at the Alpine v2 dtsi, this node was put in an io-fabric bus. It
seems to me the Alpine v3 dtsi is very similar. Would it apply as well?

Is the frequency set to 0 on purpose? Or is it set by a firmware at boot
time (if so please add a comment)?

Since you're enabling this node explicitly in the dts, you can set it to
disabled by default.

Please order the nodes in increasing order.

V3 very similar to V2, will add to io-fabric bus and will add missing
uart devices.

It's updated by firmware, will add a comment.
