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.

• 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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/soc/mediatek/mtk_sip_svc.h

Detected Declarations

• struct ufs_mtk_smc_arg
• enum ufs_mtk_vcc_num
• enum ufs_mtk_mphy_op
• function _ufs_mtk_smc

Annotation

• Immediate include surface: `linux/soc/mediatek/mtk_sip_svc.h`.
• Detected declarations: `struct ufs_mtk_smc_arg`, `enum ufs_mtk_vcc_num`, `enum ufs_mtk_mphy_op`, `function _ufs_mtk_smc`.
• Atlas domain: Driver Families / drivers/ufs.
• Implementation status: source implementation candidate.

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.
