From 6c21336acd5b2adf33ec73f43f31bd389381da5f Mon Sep 17 00:00:00 2001 From: "Richard Genoud (TI)" Date: Mon, 27 Apr 2026 16:29:01 +0200 Subject: [PATCH] arm64: dts: ti: k3-j722s: Add wakeup domain peripherals specific to J722S Introduce the "k3-j722s-mcu.dtsi" file to contain wakeup domain peripherals that are specific to J722S SoC and are not shared with AM62P. Previously, those nodes were squatting the k3-j722s-main.dtsi file which should contain only main domain peripherals.
