From 293e39780d5f03c3ce8a2b032b607a9cf161d9fc Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Wed, 4 Sep 2019 16:01:39 +0530 Subject: arm: dts: k3-j721e-main: Add C66x DSP nodes The J721E SoCs have two TMS320C66x DSP Core Subsystems (C66x CorePacs) in the MAIN voltage domain, each with a C66x Fixed/Floating-Point DSP Core, and 32 KB of L1P & L1D configurable SRAMs/Cache and an additional 288 KB of L2 configurable SRAM/Cache. These subsystems do not have an MMU but contain a Region Address Translator (RAT) sub-module for translating 32-bit processor addresses into larger bus addresses. The inter-processor communication between the main A72 cores and these processors is achieved through shared memory and Mailboxes. Add the DT nodes for these DSP processor sub-systems in the common k3-j721e-main.dtsi file.
