Subject: [PATCH 1/2] dt-bindings: soc: xilinx: Add the dt binding for Xilinx AI Engine
Date: Mon, 21 Jan 2019 17:12:16 -0800	[thread overview]
Message-ID: <1548119537-1788-1-git-send-email-hyun.kwon@xilinx.com> (raw)

Add the dt bindings for Xilinx AI Engine, which is a tile processor
with many cores. The compatible string, 'xlnx,mathengine' is kept for
backward compatibility as it's the legacy name.

+Xilinx AI Engine
+----------------
+
+The Xilinx AI Engine is a tile processor with many cores (up to 400) that
+can run in parallel. The data routing between cores is configured through
+internal switches, and shim tiles interface with external interconnect, such
+as memory or PL.
+
+Required properties:
+
+- compatible: Must be "xlnx,ai_engine", or "xlnx,mathengine" for legacy name.
+- reg: Physical base address and length of the registers set for the device.
+
+Example:
+
+	ai_engine@80000000 {
+		compatible = "xlnx,ai_engine";
+		reg = <0x0 0x80000000 0x0 0x20000000>;
+	};
