Subject: [PATCH v2 7/9] arm64: dts: imx8ulp-evk: Enable LPUART7
Date: Mon, 20 Jul 2026 22:12:15 +0800	[thread overview]
Message-ID: <20260720-imx8ulp-dts-v2-7-d05c67676f53@nxp.com> (raw)
In-Reply-To: <20260720-imx8ulp-dts-v2-0-d05c67676f53@nxp.com>

From: Sherry Sun <sherry.sun@nxp.com>

The i.MX 8ULP EVK proto1B revision routes LPUART7 TX/RX to the FT4232
PortD connector (J25/J26 pins 2-3). Enable the port by default so the
additional serial console is available out of the box.
