[PATCH v4 01/17] PCI: dwc: Use the DMA-API to get the MSI address

2017-11-03 Thread Niklas Cassel
Use the DMA-API to get the MSI address. This address will be written to our PCI config space and to the register which determines which AXI address the DWC IP will spoof for incoming MSI irqs. Since it is a PCIe endpoint device, rather than the CPU, that is supposed to write to the MSI address, th
