Since UIC1 is cascaded off UIC0 in the interrupt tree, UIC1 should have an interrupt-parent pointing to UIC0 so the interrupt tree can be traversed to the root.Not necessary if UIC0 is the device tree parent of UIC1. (And in fact it would be "bad style"). But...quoted
I know this was beaten to death last week, but I would still argue that in the device tree UIC0 and UIC1 should be siblings. (In the interrupt tree the cascade relationship is described through interrupt-parent).... that is my opinion as well (as I'm sure you know ;-) ), and then of course you _do_ need the interrupt-parent property.
Ok, there are enough people of this opinion (including Paul), that I've changed to representing the UICs as siblings. -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you. NOT _the_ _other_ | _way_ _around_! http://www.ozlabs.org/~dgibson
