The same compatible is used for other SoCs. Even if the code is same I was thinking to keep the compatible as below now - ti,am654-icss-iep # for K3 AM65x SoCs and once other SoCs are introduced, I will just modify the comment, - ti,am654-icss-iep # for K3 AM65x, AM64x SoCs But we can also keep the all SoCs in comment right from start as well. I am fine with both. Conor / Roger, Please let me know which approach should I go with in next revision? -- Thanks and Regards, Danish.
