Subject: [PATCH 1/7] arm64: dts: ti: k3-j721e-main: Add C66x DSP nodes
Date: Wed, 19 Aug 2020 20:03:25 -0500 [thread overview]
Message-ID: <20200820010331.2911-2-s-anna@ti.com> (raw)
In-Reply-To: <20200820010331.2911-1-s-anna@ti.com>
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.
The following firmware names are used by default for these cores, and
can be overridden in a board dts file if desired:
C66x_0 DSP: j7-c66_0-fw
C66x_1 DSP: j7-c66_1-fw
