Annotated Snippet
Note:
This documents additional properties of any device beyond what
is documented in Documentation/admin-guide/sysfs-rules.rst
What: /sys/devices/*/of_node
Date: February 2015
Contact: Device Tree mailing list <devicetree@vger.kernel.org>
Description:
Any device associated with a device-tree node will have
an of_path symlink pointing to the corresponding device
node in /sys/firmware/devicetree/
What: /sys/devices/*/devspec
Date: October 2016
Contact: Device Tree mailing list <devicetree@vger.kernel.org>
Description:
If CONFIG_OF is enabled, then this file is present. When
read, it returns full name of the device node.

Contact: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Description:
Major and minor numbers of the character device corresponding
to the device (in <major>:<minor> format).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.
