enhancement: addition of /delete-label/

[de-nordic]

Currently it is not possible to delete label independently from deleting entire node.

This is very inconvenient because it does not allow to move labels from node to node, when needed, without redefining
the node again.

References to labels may be used for property values (or as phandles), but when referenced node needs to be changed, due to lack of /delete-label/, it is required to remove property referencing the label for each node and then add it back referencing node with different label. This could be much easier if label could be removed from one node and added to another.

The first step here is to implement this for dtc or propose the concept on the dtc maillist.

The spec is already not complete in terms of DTS directives. For example /bits/, /omit-if-no-ref/, and /incbin/ are all not in the spec. Perhaps that should be a requirement, but it is not ATM.

In any case, submitting a GH issue here is not going to get you a feature. There is no one working on spec enhancements.

Thank you for response. I thought that specification states what DT compilers should implement, that is why I have proposed the enhancement here.

While that makes sense, the reality is that the spec and dtc are not that decoupled. And proposing this for dtc will get wider review.
