    SubjectQuestion 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 !
