  dt-bindings: iommu: riscv: Add bindings for Tenstorrent RISC-V IOMMU (2026-05-23 17:14:35 -0700)

----------------------------------------------------------------
Tenstorrent device tree for v7.2

Add a riscv,pmu node to the Tenstorrent Blackhole SoC device tree. This
enables OpenSBI to expose the SBI PMU extension, allowing Linux perf to
use the 4 programmable counters (mhpmcounter3-6) across 3 event classes:
instruction commit, microarchitectural, and memory system events.

Extend the RISC-V IOMMU device tree bindings to document the Tenstorrent
IOMMU used in the Tenstorrent Atlantis SoC. A second register range is
added which contains M-mode only registers like PMAs and PMPs. The
binding will be used by OpenSBI and potentially other M-mode software.
