Typically, we use macros in C to access nodes. The principle involves concatenating basic properties and retrieving constants from devicetree_generated.h. I believe we can start by extracting C macro constants from Rust.
(If possible, it can be assigned to me, although I am not familiar with rust. But I think I can try to accept it.)

@d3zd3z How far are you thinking of taking this for the initial implementation/milestone?

For non-phandle properties, I think one could take a similar approach to the Kconfig stuff; e.g. use build.rs and a bunch of parsing logic to generate code for a struct (of structs) that roughly mirror the devicetree's structure.

However, not sure what you were thinking for

1. phandles (self referential structs are always tough in rust)
2. strong typing of the nodes (likely via parsing of the assorted binding yaml files?)
3. struct device* access from rust

Let's brainstorm through these sometime soon!

edit: nevermind, I see you have already done a significant amount of implementation in #15 . Please let me know if there is anything I can help with there.
