  This controller on Tegra family SoCs provides an interface for MMC, SD, and
  SDIO types of memory cards.

  This file documents differences between the core properties described by
  mmc-controller.yaml and the properties for the Tegra SDHCI controller.

Atlas domain: Support Tooling And Documentation / Documentation.
Implementation status: atlas-only.

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.
