Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an undesirable API for the following reasons: - it's inconsistent with the rest of the DT_NODE_HAS_FOO names - DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand for macros which are equivalent to DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) && - DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck - DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway - it is seen as a somewhat aesthetically challenged name Replace all users with DT_NODE_HAS_STATUS(..., okay), which is semantically equivalent. This is mostly done with sed, but a few remaining cases were done by hand, along with whitespace, docs, and comment changes. These special cases include the Nordic SOC static assert files.
