From 46ab8238e3e81669c41c698460583636e811018e Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Fri, 24 Apr 2020 18:12:29 +0300 Subject: ARM: dts: DRA7: Add common IPU and DSP nodes The DRA7xx family of SOCs have two IPUs and upto two DSP processor subsystems in general. The IPU processor subsystem contains dual-core ARM Cortex-M4 processors, while the DSP processor subsystem is based on the TI's standard TMS320C66x DSP CorePac core. The IPUs are very similar to those on OMAP5. Two IPUs and one DSP processor subsystems is the most common configuration. The processor device DT nodes have been added for these processor subsystems, with the internal memories added through 'reg' and 'reg-names' properties. The IPUs only have an L2 RAM, whereas the DSPs have L1P, L1D and L2 RAM memories. NOTE: 1. The nodes do not have any mailboxes, timers or CMA regions assigned, they should be added in the respective board dts files. 2. The nodes haven been disabled by default and the enabling of these nodes is also left to the respective board dts files.
