title: Amlogic Meson SoC UART Serial Interface

maintainers:
  - Neil Armstrong <neil.armstrong@linaro.org>

description: |
  The Amlogic Meson SoC UART Serial Interface is present on a large range
  of SoCs, and can be present either in the "Always-On" power domain or the
  "Everything-Else" power domain.

  The particularity of the "Always-On" Serial Interface is that the hardware
  is active since power-on and does not need any clock gating and is usable
  as very early serial console.

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.
