[PATCH v1 0/3] switchtec: add new device IDs

[PATCH v1 0/3] switchtec: add new device IDs

[Logan Gunthorpe]

This little patch set adds some new device IDs for switchtec hardware
to the PCI driver, the DMA driver and the PCI quirk needed for NTB.

I originally included this in a patchset I'm working on for
switchtec-dma but the Sashiko bot reminded me I need to add it to the
PCI management device and the quirk used for NTB. So I've respun three
patches here.

I'm open to options, but I might suggest if everyone is okay with it
these three patches could just go through the PCI tree together.

These three patches are based on v7.2-rc3.

Thanks,

Logan

[PATCH v1 2/3] PCI/switch: switchtec: Add PCI1008 device ID

[Logan Gunthorpe]

Add the PCI1008 device ID to the core switchtec management
driver's PCI ID table. Without it, the management endpoint on a
PCI1008 switch is not bound by this driver, preventing userspace
tools from configuring or monitoring the switch and leaving NTB
functionality unavailable.

[PATCH v1 3/3] PCI: Add PCI1008 to switchtec NTB DMA alias quirk

[Logan Gunthorpe]

Add the PCI1008 device ID to the quirk_switchtec_ntb_dma_alias
PCI fixup table. Without it, DMA transactions from a PCI1008 switch's
NTB function are not given the correct requester ID alias, which can
misdirect them under an IOMMU.

Applied to pci/switchtec for v7.3, thanks!
