Hi Mark:

Thanks for your reply.

To be exact, they are similar, such as the definition of the
controller registers.
But for example, DMA data processing is different. In the pci version
of i2s, the DMA controller is built-in, while the DMA controller here
is external, using ls2x-apbdma (drivers/dma/ls2x-apb-dma.c)

Thanks.
