Dcsky,apb-intc.txt2 C-SKY APB Interrupt Controller
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.
