(This and patch > subject "[PATCH 1/2] pci: pci_ids: Move Synopsys HAPS platform device IDs") 1) Run "git log --oneline drivers/pci/quirks.c" ... 2) quirk_amd_nl_class() and quirk_netmos() do something similar in a different way. quirk_amd_nl_class() in particular seems to be doing exactly the same thing. I think since they're doing the same thing, they should do it the same way. Would the quirk_amd_nl_class() solution work for you? Bjorn

Also, the way Netmos handling multiple devices is cleaner. I'll incorporate the their solutions. Thanks, Thinh

Synopsys USB 3.x host HAPS platform has a class code of PCI_CLASS_SERIAL_USB_XHCI, and xhci driver can claim it. However, these devices should use dwc3-haps driver. Set driver_override to dwc3-haps for these platforms. Signed-off-by: Thinh Nguyen <thinhn@synopsys.com> --- drivers/pci/quirks.c | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+)
