12description: >
13  C-SKY APB Interrupt Controller is a simple soc interrupt controller on the apb
14  bus and we only use it as root irq controller.
15
16    - csky,apb-intc is used in a lot of csky fpgas and socs, it support 64 irq nums.
17    - csky,dual-apb-intc consists of 2 apb-intc and 128 irq nums supported.
18    - csky,gx6605s-intc is gx6605s soc internal irq interrupt controller, 64 irq nums.
