+Subject: [PATCH] rockchip: rk3568: Add support for FriendlyARM NanoPi R5C
+
+FriendlyARM NanoPi R5C is an open-sourced mini IoT gateway device.
+
+Specification:
+- Rockchip RK3568
+- 1/4GB LPDDR4X RAM
+- 8/32GB eMMC
+- SD card slot
+- M.2 Connector
+- 2x USB 3.0 Port
+- 2x 2500 Base-T (PCIe, r8125)
+- HDMI 2.0
+- MIPI DSI/CSI
+- USB Type C 5V
+
+The device tree is taken from kernel v6.4-rc1.
