Isn't that feasible? > We can worry about domain unification later. I think that's what we were trying to avoid, adding an arm64-specific pci_sys_data structure (and arm64-specific API). IIUC, avoiding this would allow the host controller drivers to use the sysdata pointer for their own private data structures. Also since you can specify the domain number via DT (and in Liviu's v8 patches read by of_create_pci_host_bridge), I think it would make sense to have it stored in some generic data structures (e.g. pci_host_bridge) rather than in an arm64 private sysdata. (Liviu is thinking of an alternative API but maybe he could briefly describe it here before posting a new series) -- Catalin -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
