I assume this ordering requirement applies to both Cadence and DesignWare, i.e., drivers/pci/endpoint must be linked before drivers/pci/cadence and drivers/pci/dwc. If so, please add a one-line comment in the Makefile, e.g., obj-$(CONFIG_PCI_ENDPOINT) += endpoint/ # endpoint library must be initialized before its users obj-$(CONFIG_PCI_CADENCE) += cadence/ obj-y += dwc/ I think the "PCI dwc controller drivers" comment adds no real value. > > diff --git a/drivers/pci/Makefile b/drivers/pci/Makefile > > index 7284a7f6ad1e..a66ddb347798 100644 > > --- a/drivers/pci/Makefile > > +++ b/drivers/pci/Makefile > > @@ -54,5 +54,6 @@ obj-y += host/ > > obj-y += switch/ > > > > obj-$(CONFIG_PCI_ENDPOINT) += endpoint/ > > +obj-$(CONFIG_PCI_CADENCE) += cadence/ > > # PCI dwc controller drivers > > obj-y += dwc/ -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
