am335x在设备树中如何定义事件映射?

Other Parts Discussed in Thread: AM3352

am3352通过gpmc连接cpld在不使用dma的情况下已能很好地工作,但企图通过dma从gpmc总线上读数据时出错。

使用xdma_event_intr1引脚作为事件触发信号,如何将xdma_event_intr1引脚信号同dma的事件关联起来,我在设备树中是这样定义的:

&edma {

              ti,edma-xbar-event-map = < 1 12

                                                           2 13

                                                          29 14>;

             };

请高手帮我看看,这样定义是否正确?

先谢谢了!
