Sorry for the delay in reply I was on leave for the last couple weeks. There are few reasons for these: ---> We (Xilinx) have 3 different DMA's and in order to make consistency b/w the three dma's used the child node concepts so that users can easily compare the drivers ---> It is a soft IP so features like (multiple channels, cyclic dma mode) may added in nearby future so for future driver changes it will be straight forward. Please let me know if it is wrong will fix it and will send the next version of the path.
