2 C-SKY APB Interrupt Controller
3 ==============================
5 C-SKY APB Interrupt Controller is a simple soc interrupt controller
6 on the apb bus and we only use it as root irq controller.
8 - csky,apb-intc is used in a lot of csky fpgas and socs, it support 64 irq nums.
9 - csky,dual-apb-intc consists of 2 apb-intc and 128 irq nums supported.
10 - csky,gx6605s-intc is gx6605s soc internal irq interrupt controller, 64 irq nums.
