title: NVIDIA Tegra186 timer

description: >
The Tegra timer provides 29-bit timer counters and a 32-bit timestamp
counter. Each NV timer selects its timing reference signal from the 1 MHz
reference generated by USEC, TSC or either clk_m or OSC. Each TMR can be
programmed to generate one-shot, periodic, or watchdog interrupts.

Annotation
- Immediate include surface: `dt-bindings/interrupt-controller/arm-gic.h`, `dt-bindings/interrupt-controller/irq.h`.
- 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.
