title: Blaize BLZP1600 GPIO controller
description:
Blaize BLZP1600 GPIO controller is an implementation of the VeriSilicon
APB GPIO v0.2 IP block. It has 32 ports each of which are intended to be
represented as child nodes with the generic GPIO-controller properties
as described in this binding's file.

- Atlas domain: Support Tooling And Documentation / Documentation.
- 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.
