The corresponded compatible is following.
+-----+ +---------+
| GIC |---| INTC0 | -> (parent : aspeed,ast2700-intc0)
+-----+ +---------+
+---------+
| |---module0
| INTC0_0 |---module1
(child : aspeed,ast2700-intc-ic)
| |---...
+---------+---module31
|---.... |
+---------+
| | +---------+
| INTC0_11 | +---------------------------- | INTC1 | -> -> (parent : aspeed,ast2700-intc1)
(child : aspeed,ast2700-intc-ic)
| | +---------+
+---------+ +-------- -+---module0
| INTC1_0 | --> (child : aspeed,ast2700-intc-ic)
| |---...
+--------- +---module31
...
+--------- +---module0
| INTC1_5 | --> ((child : aspeed,ast2700-intc-ic))
