I don't think anyone else is currently working on further DT conversion, though Robert Jarzmik and Daniel Mack have done the important preparation work for this in the past, and Linus Walleij is looking at it across multiple platforms, so they can probably give more helpful advice than I can. There is a pxa27x.dtsi file that you can include in a new pxa270-spitz.dts file, but there are no other dts files that include this, so it's likely that there are mistakes in the description. The approach I would use is to start with a minimal dts file and get the console uart working in qemu, then add more devices one at a time by creating nodes for the devices that already have DT support, and after that create DT bindings for devices that don't have one yet, using the raumfeld files as a template. Feel free to ask on the #armlinux IRC channel on irc.libera.chat when you run into problems.
