Change the type of phybase to dma_addr_t
It should be: slave_config->dst_addr = (dma_addr_t)(ssc->phybase + SSC_THR); slave_config->src_addr = (dma_addr_t)(ssc->phybase + SSC_RHR);
The type of phybase in the ssc_device struct should be changed from resource_size_t to dma_addr_t.
Actually, the phybase in ssc_device structure is resource_size_t which used to access the ssc device register. Here, we use ssc register as dma source address or destination address, so we convert it to dma_addr_t type. So, not need to change, am I right?
Isn't 'regs' used to access the registers? As far as I can see phybase is only used in the audio DMA driver.
