Side question, in your point of view, how is that better ? current DT tools are not able to validate a file wrt its schema, so for now we just moved platdata to DTS files and lost compiler type checking in between. I respectfully understand people fighting for *stable* DT because I see the benefits behind this, even if IMO they absolutely do not outweigh the pain. But I fail to see any benefits of "forever unstable" DT, if you have to tie the kernel tree with a DTB file, the description could have been left in C code. -- Maxime -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
