ARM Microchip SoCs (aka AT91)
=============================
Introduction
------------
This document gives useful information about the ARM Microchip SoCs that are
currently supported in Linux Mainline (you know, the one on kernel.org).
It is important to note that the Microchip (previously Atmel) ARM-based MPU
product line is historically named "AT91" or "at91" throughout the Linux kernel
development process even if this product prefix has completely disappeared from
the official Microchip product name. Anyway, files, directories, git trees,
git branches/tags and email subject always contain this "at91" sub-string.
AT91 SoCs
---------
Documentation and detailed datasheet for each product are available on
the Microchip website: http://www.microchip.com.

Annotation
- 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.
