Early feedback: depending on when this goes upstream, we may
need a few more:

+ ohci0: usb@11e10000 {
+ /* placeholder */
+ };
+
+ ohci1: usb@11e90000 {
+ /* placeholder */
+ };
+
+ ehci0: usb@11e10100 {
+ /* placeholder */
+ };
+
+ ehci1: usb@11e90100 {
+ /* placeholder */
+ };
+
+ hsusb: usb@11e30000 {
+ /* placeholder */
+ };
+
+ pcie: pcie@11e40000 {
+ /* placeholder */
+ };

Gr{oetje,eeting}s,
