I'm not yet sure if I like that approach. The other option I'm considering
and also tend to prefer at the moment would be to have this in a
rk3229.dtsi, creating a chain of
	rk322x.dtsi
		\- rk3228-evb.dts
		\- rk3229.dtsi
			\- rk3229-evb.dts

similar to what we do with the rk3xxx.dtsi -> rk3188.dtsi.

If I remember correctly, there are some other tiny differences between the
rk3228 and rk3229, so having the rk3229.dtsi already would make it
easier to place needed stuff into it later on.

That makes sense, I will amend that based on your comments.
