|  | C-SKY APB Interrupt Controller is a simple soc interrupt controller on the apb | 
|  | bus and we only use it as root irq controller. | 
|  |  | 
|  | - csky,apb-intc is used in a lot of csky fpgas and socs, it support 64 irq nums. | 
|  | - csky,dual-apb-intc consists of 2 apb-intc and 128 irq nums supported. | 
|  | - csky,gx6605s-intc is gx6605s soc internal irq interrupt controller, 64 irq nums. |
