+From: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
+
+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.
