Subject: Question about DMA

Hello,

I have 2 questions regarding set_dma_addr(unsigned int channel,
unsigned int addr) helper.

1/  Why does the function take only one address ? I would expect it
to take both a source and a destination address for the dma controller
to transfer data.

2/ The type of address parameter is an unsigned int. Why isn't it a dma_addr_t
type ?

Thanks !
