description: |+
  Each Samsung UART should have an alias correctly numbered in the "aliases"
  node, according to serialN format, where N is the port number (non-negative
  decimal integer) as specified by User's Manual of respective SoC.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
