Why This File Exists

Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.

• Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/i2c.h
• linux/export.h
• linux/irqdomain.h

Detected Declarations

• struct max8997_dev
• enum max8997_pmic_reg
• enum max8997_muic_reg
• enum max8997_haptic_reg

Annotation

• Immediate include surface: `linux/i2c.h`, `linux/export.h`, `linux/irqdomain.h`.
• Detected declarations: `struct max8997_dev`, `enum max8997_pmic_reg`, `enum max8997_muic_reg`, `enum max8997_haptic_reg`, `enum max8997_rtc_reg`, `enum max8997_irq_source`, `enum max8997_irq`, `enum max8997_types`.
• Atlas domain: Core OS / Core Kernel Interface.
• 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.
