Is this dts upstream?
No, not yet. This is the smallest required DTS for this board (and hence it is a subset of the full blown Linux kernel DTS).
(Shall it be first accepted to the Linux kernel?)
Everything that's not -u-boot.dtsi stuff needs to be at least in linux-next first, yes. For all SoCs, not just am33xx.
But then I do have a question - what if I don't need the whole DTS accepted to Linux?
Would it be OK, to provide just a subset (to save space)?
If it's something that belongs to a U-Boot binding we haven't upstreamed, it goes in -u-boot.dtsi. Otherwise it goes in the full DTS which gets upstreamed, even if the kernel doesn't use it, since that's where DTS files live currently.
