From 1b846fc24d80ceb358312b4aa3e8242d36784fe4 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Wed, 4 Sep 2019 16:01:40 +0530 Subject: [PATCH] arm: dts: k3-j721e-main: Add C71x DSP node The J721E SoCs have a single TMS320C71x DSP Subsystem in the MAIN voltage domain containing the next-generation C711 CPU core. The subsystem has 32 KB of L1D configurable SRAM/Cache and 512 KB of L2 configurable SRAM/Cache. This subsystem has a CMMU but is not used currently. The inter-processor communication between the main A72 cores and the C711 processor is achieved through shared memory and a Mailbox. Add the DT node for this DSP processor sub-system in the common k3-j721e-main.dtsi file.
