Thanks for the suggestion. Installing the existing CoolPi 4B DTB under a different filename would solve the DTB naming issue, but the model and compatible properties would still identify the device as a CoolPi 4B. This is my main concern. Users running Linux on a Sige7s would still see "RK3588S CoolPi 4 Model B" in /proc/device-tree/model, even though they purchased an ArmSoM Sige7s. I agree that we should avoid duplicating the hardware description, since the boards are identical. However, I think preserving the correct board identity in the device tree is useful, especially for a product that is still being manufactured and will receive ongoing upstream support. Would it be acceptable to share the entire hardware description while keeping separate model and compatible properties for the two boards? Best regards, Jianfeng
