On further testing, by bailing out in the presence of clocks and/or
power-domains, the problem I now see is that although the primary gic-400
has been registered, we still try to probe it again later as it matches
the platform driver. One way to avoid this would be ...
diff --git a/drivers/of/irq.c b/drivers/of/irq.c
index e7bfc175b8e1..631da7ad0dbf 100644

*/
list_add_tail(&desc->list, &intc_parent_list);
+
+ of_node_set_flag(desc->dev, OF_POPULATED);
}
If this is not appropriate then I guess I will just need to use
"tegra210-agic" for the compatibility flag.
Cheers
Jon
