From 388e5c51135f817f01177c42261f1116a6d7f2ad Mon Sep 17 00:00:00 2001 From: Vivek Gautam Date: Tue, 15 Jan 2013 16:09:21 +0530 Subject: usb: dwc3: remove dwc3 dependency on host AND gadget. DWC3 controller curretly depends on USB && USB_GADGET. Some hardware may like to use only host feature on dwc3, or only gadget feature. So, removing this dependency of USB_DWC3 on USB and USB_GADGET. Adding the mode of operaiton of DWC3 also here HOST/GADGET/DUAL_ROLE based on which features are enabled. [ balbi@ti.com : . make sure we have default modes for all possible Kernel configurations. . Remove the config -> menuconfig change as it's unnecessary . switch over to IS_ENABLED() ] CC: Doug Anderson Signed-off-by: Vivek Gautam Signed-off-by: Felipe Balbi --- drivers/usb/dwc3/core.h | 16 +++++++++++++++- 1 file changed, 15 insertions(+), 1 deletion(-) (limited to 'drivers/usb/dwc3/core.h') diff --git a/drivers/usb/dwc3/core.h b/drivers/usb/dwc3/core.h index f02b3e0795e0..b41750660235 100644 --- a/drivers/usb/dwc3/core.h +++ b/drivers/usb/dwc3/core.h @@ -864,10 +864,24 @@ union dwc3_event { void dwc3_set_mode(struct dwc3 *dwc, u32 mode); int dwc3_gadget_resize_tx_fifos(struct dwc3 *dwc); +#if IS_ENABLED(CONFIG_USB_DWC3_HOST) || IS_ENABLED(CONFIG_USB_DWC3_DUAL_ROLE) int dwc3_host_init(struct dwc3 *dwc); void dwc3_host_exit(struct dwc3 *dwc); - +#else +static inline int dwc3_host_init(struct dwc3 *dwc) +{ return 0; } +static inline void dwc3_host_exit(struct dwc3 *dwc) +{ } +#endif + +#if IS_ENABLED(CONFIG_USB_DWC3_GADGET) || IS_ENABLED(CONFIG_USB_DWC3_DUAL_ROLE) int dwc3_gadget_init(struct dwc3 *dwc); void dwc3_gadget_exit(struct dwc3 *dwc); +#else +static inline int dwc3_gadget_init(struct dwc3 *dwc) +{ return 0; } +static inline void dwc3_gadget_exit(struct dwc3 *dwc) +{ } +#endif #endif /* __DRIVERS_USB_DWC3_CORE_H */ -- cgit v1.2.1
