PCI: brcmstb: Add MSI support

2020-01-28T13:54:15+00:00

This adds MSI support to the Broadcom STB PCIe host controller. The MSI controller is physically located within the PCIe block, however, there is no reason why the MSI controller could not be moved elsewhere in the future. MSIX is not supported by the HW. Since the internal Brcmstb MSI controller is intertwined with the PCIe controller, it is not its own platform device but rather part of the PCIe platform device.

PCI: vmd: Remove dma_map_ops overrides

2020-01-24T20:58:59+00:00

Devices on the VMD domain use the VMD endpoint's requester ID and have been relying on the VMD endpoint's DMA operations. The problem with this was that VMD domain devices would use the VMD endpoint's attributes when doing DMA and IOMMU mapping. We can be smarter about this by only using the VMD endpoint when mapping and providing the correct child device's attributes during DMA operations. Remove the dma_map_ops redirect.
