Subject: [PATCH V2 1/3] dt-bindings: dma: xilinx: Add optional resets property for ZDMA
Date: Thu, 18 Jun 2026 12:40:54 +0530	[thread overview]
Message-ID: <20260618071056.2024286-2-nagendra.golla@amd.com> (raw)
In-Reply-To: <20260618071056.2024286-1-nagendra.golla@amd.com>

From: Jay Buddhabhatti <jay.buddhabhatti@amd.com>

Newer SoCs such as Versal Gen2 and Versal‑Net expose a reset line
for ZDMA. Older SoCs do not have this provision. Add an optional
resets property to describe this reset.
