[PATCH 0/2] More switchtec device IDs

[PATCH 0/2] More switchtec device IDs

[Logan Gunthorpe]

These patches add some missing device IDs to the PCI quirk and the
dmaengine driver. The same device ID was added to the main PCI driver
back in commit 5e6c21c56998 ("PCI: switchtec: Add Gen6 Device IDs").

As, like last time, these patches touch both the PCI and
the dmaengine tree so I'll humbly suggest that they
go through the PCI tree again.

Thanks,

Logan

[PATCH 1/2] dmaengine: switchtec-dma: Add Gen6 secure device IDs

[Logan Gunthorpe]

Add the device IDs for the Gen6 PFXs and PSXs secure switches
(48XG6 and 64XG6) so switchtec-dma binds to their DMA functions.

[PATCH 2/2] PCI: switchtec: Add Gen6 secure switches to NTB DMA alias quirk

[Logan Gunthorpe]

Add the Gen6 PFXs and PSXs secure switch device IDs (48XG6 and 64XG6)
to the quirk_switchtec_ntb_dma_alias PCI fixup table. Without them,
DMA transactions from these switches' NTB function are not given the
correct requester ID alias, which can misdirect them under an IOMMU.

Applied to pci/switchtec for v7.5, thanks!
