+Subject: [PATCH] arm64: dts: rockchip: Add rk3566 based Radxa Compute Module 3
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Radxa Compute Module 3(CM3) is one of the modules from a series
+System On Module based on the Radxa ROCK 3 series and is compatible
+with Raspberry Pi CM4 pinout and form factor.
+
+Specification:
+- Rockchip RK3566
+- up to 8GB LPDDR4
+- up to 128GB high performance eMMC
+- Optional wireless LAN, 2.4GHz and 5.0GHz IEEE 802.11b/g/n/ac wireless,
+ BT 5.0, BLE with onboard and external antenna.
+- Gigabit Ethernet PHY
+
+Radxa CM3 needs to mount on top of this IO board in order to create
+complete Radxa CM3 IO board platform.
+
+Since Radxa CM3 is compatible with Raspberry Pi CM4 pinout so it is
+possible to mount Radxa CM3 on top of the Rasberry Pi CM4 IO board.
+
+Add support for Radxa CM3.
