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.
