+Subject: [PATCH] arm64: dts: rockchip: Add Radxa CM3I E25
+
+Radxa E25 is a network application carrier board for the Radxa CM3
+Industrial (CM3I) SoM, which is based on the Rockchip RK3568 SoC.
+
+It has the following features:
+
+- MicroSD card socket, on board eMMC flash
+- 2x 2.5GbE Realtek RTL8125B Ethernet transceiver
+- 1x USB Type-C port (Power and Serial console)
+- 1x USB 3.0 OTG port
+- mini PCIe socket (USB or PCIe)
+- ngff PCIe socket (USB or SATA)
+- 1x User LED and 16x RGB LEDs
+- 26-pin expansion header
