Subject: [PATCH v2 2/3] arm64: dts: ti: k3-j722s: Add mcu domain peripherals specific to J722S
Date: Mon, 27 Apr 2026 16:29:00 +0200 [thread overview]
Message-ID: <20260427142901.341861-3-richard.genoud@bootlin.com> (raw)
In-Reply-To: <20260427142901.341861-1-richard.genoud@bootlin.com>
Introduce the "k3-j722s-mcu.dtsi" file to contain mcu 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.
