This is a one-line fix for edtlib, which lets gen_defines.py indicate whether the `ranges` property exists within a given node. Although address translation through ranges is typically automatic, users can choose to manually inspect ranges using DT_FOREACH_RANGE(), DT_NUM_RANGES(), and other DT_RANGES_* macros. These can be used to implement manual translation at runtime, which is currently done for PCIe controllers. The only thing missing is being able to check if a node contains an empty `ranges;`, which signifies a 1:1 translation to the parent bus. Checking DT_NUM_RANGES() is insufficient, because it returns zero whether or not `ranges;` is present. It should be possible to use DT_NODE_HAS_PROP(), but it was not working, because edtlib ignores properties which are undeclared in bindings and don't have a default type. Add a missing PropertySpec for `ranges` with "compound" type; it can't be "array" because it can be empty-valued. Signed-off-by: Grzegorz Swiderski <grzegorz.swiderski@nordicsemi.no> |
