Annotated Snippet
Widgets:
This mainly specifies audio off-codec DAPM widgets.
Each entry is a pair of strings in DT:
"template-wname", "user-supplied-wname"
The "template-wname" being the template widget name and currently includes:
"Microphone", "Line", "Headphone" and "Speaker".
The "user-supplied-wname" being the user specified widget name.
For instance:
simple-audio-widgets =
"Microphone", "Microphone Jack",
"Line", "Line In Jack",
"Line", "Line Out Jack",
"Headphone", "Headphone Jack",
"Speaker", "Speaker External";
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.
