Add dma_dev, a pointer to struct device, to struct ssb_device. We pass it
|
|
to the generic DMA API with SSB_BUSTYPE_PCI and SSB_BUSTYPE_SSB.
|
|
ssb_devices_register() sets up it properly.
|
|
|
|
This is preparation for replacing the ssb bus specific DMA API (ssb_dma_*)
|
|
with the generic DMA API.
