From 9ca8079eb36b71a86bb5851d9d3b7a49da8e595f Mon Sep 17 00:00:00 2001 From: Beleswar Padhi Date: Mon, 8 Sep 2025 19:58:03 +0530 Subject: [PATCH] arm64: dts: ti: k3-am62a: Enable Mailbox nodes at the board level Mailbox nodes defined in the top-level AM62A SoC dtsi files are incomplete and may not be functional unless they are extended with a chosen interrupt and connection to a remote processor. As the remote processors depend on memory nodes which are only known at the board integration level, these nodes should only be enabled when provided with the above information. Disable the Mailbox nodes in the dtsi files and only enable the ones that are actually used on a given board.
