Subject: [PATCH v9 (RESEND) 1/7] dt-bindings: soc: ti: Add AM65 peripheral virtualization unit
Date: Wed, 16 Jul 2025 13:39:44 +0800	[thread overview]
Message-ID: <20250716053950.199079-2-huaqian.li@siemens.com> (raw)
In-Reply-To: <20250716053950.199079-1-huaqian.li@siemens.com>

From: Jan Kiszka <jan.kiszka@siemens.com>

The PVU allows to define a limited set of mappings for incoming DMA
requests to the system memory. It is not a real IOMMU, thus hooked up
under the TI SoC bindings.
