Hi David
In the probe function we have:
+ reg = of_get_property(pdev->dev.of_node, "reg", NULL);
+ addr = of_translate_address(pdev->dev.of_node, reg);
+ interface = (addr >> 24) & 0xf;
+ numa_node = (addr >> 36) & 0x7;
Is this documented somewhere? The numa_node is particularly
interesting. MMIO changes depends on what node this is in the cluster?
