Subject: [PATCH] arm64: dts: ti: k3-j784s4-main: disable remote proc nodes
Date:   Wed, 9 Aug 2023 19:56:29 -0500
Message-ID: <20230810005629.21738-1-hnagalla@ti.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

Disable the dsp and r5f subsystem nodes by default. Proper functioning
of remote processors with ipc need mailbox configurations which can
vary between board configurations and applications. Hence move enabling
the remote processor device nodes to where the required configurations
are complete.
