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.

	  Say y or m here to enable the power domains driver for MediaTek
	  MFlexGraphics. This driver allows for power and frequency control of
	  GPUs on MediaTek SoCs such as the MT8196 or MT6991.

	  This driver is required for the Mali GPU to work at all on MT8196 and
	  MT6991.

Annotation

Atlas domain: Driver Families / drivers/pmdomain.
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.
