The platform file will always get compiled for the case where the controller is directly connected to the CPU. So for loadable modules, dwc2.ko is built for host, peripheral, and dual-role mode. The PCI bus interface will be called dwc2_pci.ko and the platform interface module will be called dwc2_platform.ko. Signed-off-by: Dinh Nguyen Acked-by: Paul Zimmerman --- v6: Correct notes for USB_DWC2_DUAL_ROLE and USB_DWC2_PERIPHERAL Remove extra default for USB_DWC2_PLATFORM and make it a condition for building dwc2_platform.ko. In addition USB_DWC2_PLATFORM and USB_DWC2_PCI are now tristate. v5: dwc2.ko for all modes along with dwc2_platform.ko and dwc2_pci.ko will get built for kernel modules. v3: Add USB_GADGET=y and USB_GADGET=USB_DWC2 for peripheral and dual-role config options. v2: Remove reference to dwc2_gadget --- drivers/usb/dwc2/Kconfig | 66 ++++++++++++++++++++++++++++------------------- drivers/usb/dwc2/Makefile | 32 +++++++++++------------ 2 files changed, 55 insertions(+), 43 deletions(-) diff --git a/drivers/usb/dwc2/Kconfig b/drivers/usb/dwc2/Kconfig index 4d02718..b323c4c 100644 --- a/drivers/usb/dwc2/Kconfig +++ b/drivers/usb/dwc2/Kconfig @@ -1,5 +1,5 @@ config USB_DWC2 - bool "DesignWare USB2 DRD Core Support" + tristate "DesignWare USB2 DRD Core Support" depends on USB || USB_GADGET help Say Y here if your system has a Dual Role Hi-Speed USB @@ -10,49 +10,61 @@ config USB_DWC2 bus interface module (if you have a PCI bus system) will be called dwc2_pci.ko, and the platform interface module (for controllers directly connected to the CPU) will be called - dwc2_platform.ko.
