Add the following new macros: - DT_FOREACH_NODELABEL - DT_FOREACH_NODELABEL_VARGS - DT_INST_FOREACH_NODELABEL - DT_INST_FOREACH_NODELABEL_VARGS These are for-each helpers for iterating over the node labels of a devicetree node. Since node labels are unique in the entire devicetree, their token representations can be useful as unique IDs in code as well. As a first user of these, add: - DT_NODELABEL_STRING_ARRAY - DT_INST_NODELABEL_STRING_ARRAY The motivating use case for these macros is to allow looking up a struct device by devicetree node label in Zephyr shell utilities. The work on the shells themselves is deferred to other patches. To make working with the string array helpers easier, add: - DT_NUM_NODELABELS - DT_INST_NUM_NODELABELS Signed-off-by: Martí Bolívar <mbolivar@amperecomputing.com> |
