title: AXP20x USB power-supply

description: |
  The AXP223 PMIC shares most of its behaviour with the AXP221 but has slight
  variations such as the former being able to set the VBUS power supply max
  current to 100mA, unlike the latter.

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.
