Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

config PM_OPP
	bool

	  SOCs have a standard set of tuples consisting of frequency and
	  voltage pairs that the device will support per voltage domain. This
	  is called Operating Performance Point or OPP. The actual definitions
	  of OPP varies over silicon within the same family of devices.

	  OPP layer organizes the data internally using device pointers
	  representing individual voltage domains and provides SOC
	  implementations a ready to use framework to manage OPPs.

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.
