Subject: [PATCH 1/2] arm64: dts: ti: k3-am62p: Enable Mailbox nodes at the board level
Date: Tue, 3 Dec 2024 11:41:13 -0600 [thread overview]
Message-ID: <20241203174114.94751-1-afd@ti.com> (raw)
Mailbox nodes defined in the top-level J722s/AM62p SoC dtsi files are
incomplete and may not be functional unless they are extended with a
chosen interrupt and connection to a remote processor.
Disable the Mailbox nodes in the dtsi files and only enable the ones
that are actually used on a given board.
Signed-off-by: Andrew Davis <afd@ti.com>
