Subject: [PATCH v2 2/2] arm64: dts: rockchip: Add Khadas Edge 2L board
Date: Tue, 17 Mar 2026 17:07:31 +0800 [thread overview]
Message-ID: <20260317090731.600787-3-gray.huang@wesion.com> (raw)
In-Reply-To: <20260317090731.600787-1-gray.huang@wesion.com>
The Khadas Edge 2L is a single board computer based on the Rockchip
RK3576 SoC.
Add basic device tree support for this board. Currently, only eMMC
and UART are enabled, allowing the board to boot into a basic Linux
system via the serial console.
