You're not even willing to try a patch, rather than complaining > about pointless stuff all day. Thanks > The reason why I did not try your patch is: I don't think the PHY needs to depend on GADGET since your 1st patch like below: + depends on USB_GADGET=y || USB_GADGET=NOP_USB_XCEIV + depends on NOP_USB_XCEIV But look at your the newest patch, you have fixed it like below: + depends on USB_GADGET || !USB_GADGET # if USB_GADGET=m, NOP can't be built-in I agree with that since PHY can not depend on GADGET if it does not use gadget APIs. After trying your patch, you only fixed NOP PHY build issue (chipidea build issue is fixed too), but without for other code. You may need to fix all like my last grep: b29397@shlinux2:~/work/projects/usb$ find . -name *.c | xargs grep -rn "usb_gadget_vbus_connect" ./drivers/phy/phy-twl4030-usb.c:559: * REVISIT usb_gadget_vbus_connect(...) as needed, ditto ./drivers/usb/phy/phy-gpio-vbus-usb.c:126: usb_gadget_vbus_connect(gpio_vbus->phy.otg->gadget); ./drivers/usb/phy/phy-tahvo.c:89: usb_gadget_vbus_connect(tu->phy.otg->gadget); ./drivers/usb/phy/phy-isp1301-omap.c:929: usb_gadget_vbus_connect(isp->phy.otg->gadget); ./drivers/usb/phy/phy-isp1301-omap.c:1466: usb_gadget_vbus_connect(otg->gadget); ./drivers/usb/phy/phy-generic.c:122: usb_gadget_vbus_connect(otg->gadget); ./drivers/usb/phy/phy-generic.c:190: usb_gadget_vbus_connect(gadget); ./drivers/usb/phy/phy-msm-usb.c:783: usb_gadget_vbus_connect(phy->otg->gadget); ./drivers/usb/phy/phy-mv-usb.c:234: usb_gadget_vbus_connect(otg->gadget); ./drivers/usb/chipidea/otg.c:133: usb_gadget_vbus_connect(&ci->gadget); ./drivers/usb/chipidea/otg.c:138: usb_gadget_vbus_connect(&ci->gadget); ./drivers/usb/chipidea/udc.c:1964: usb_gadget_vbus_connect(&ci->gadget); ./drivers/usb/chipidea/otg_fsm.c:567: usb_gadget_vbus_connect(&ci->gadget); b29397@shlinux2:~/work/projects/usb$ find . -name *.c | xargs grep -rn "usb_gadget_vbus_disconnect" ./drivers/usb/phy/phy-gpio-vbus-usb.c:145: usb_gadget_vbus_disconnect(gpio_vbus->phy.otg->gadget); ./drivers/usb/phy/phy-gpio-vbus-usb.c:200: usb_gadget_vbus_disconnect(otg->gadget); ./drivers/usb/phy/phy-tahvo.c:108: usb_gadget_vbus_disconnect(tu->phy.otg->gadget); ./drivers/usb/phy/phy-tahvo.c:165: usb_gadget_vbus_disconnect(tu->phy.otg->gadget); ./drivers/usb/phy/phy-tahvo.c:175: usb_gadget_vbus_disconnect(tu->phy.otg->gadget); ./drivers/usb/phy/phy-isp1301-omap.c:312: return usb_gadget_vbus_disconnect(isp->phy.otg->gadget); ./drivers/usb/phy/phy-isp1301-omap.c:989: usb_gadget_vbus_disconnect(otg->gadget); ./drivers/usb/phy/phy-isp1301-omap.c:1342: usb_gadget_vbus_disconnect(otg->gadget); ./drivers/usb/phy/phy-generic.c:133: usb_gadget_vbus_disconnect(otg->gadget); ./drivers/usb/phy/phy-fsl-usb.c:622: usb_gadget_vbus_disconnect(otg->gadget); ./drivers/usb/phy/phy-msm-usb.c:786: usb_gadget_vbus_disconnect(phy->otg->gadget); ./drivers/usb/phy/phy-mv-usb.c:236: usb_gadget_vbus_disconnect(otg->gadget); ./drivers/usb/chipidea/otg.c:140: usb_gadget_vbus_disconnect(&ci->gadget); ./drivers/usb/chipidea/otg_fsm.c:569: usb_gadget_vbus_disconnect(&ci->gadget); b29397@shlinux2:~/work/projects/usb$ find . -name *.c | xargs grep -rn "usb_gadget_connect" ./drivers/power/isp1704_charger.c:272: usb_gadget_connect(isp->phy->otg->gadget); ./drivers/usb/gadget/udc/fsl_udc_core.c:1215: * this func is used by usb_gadget_connect/disconnet ./drivers/usb/gadget/udc/udc-core.c:262: usb_gadget_connect(udc->gadget); ./drivers/usb/gadget/udc/udc-core.c:671: usb_gadget_connect(udc->gadget); ./drivers/usb/chipidea/udc.c:1593: * this func is used by usb_gadget_connect/disconnet b29397@shlinux2:~/work/projects/usb$ find . -name *.c | xargs grep -rn "usb_gadget_disconnect" ./drivers/power/isp1704_charger.c:302: usb_gadget_disconnect(isp->phy->otg->gadget); ./drivers/power/isp1704_charger.c:504: usb_gadget_disconnect(isp->phy->otg->gadget); ./drivers/usb/gadget/udc/udc-core.c:264: usb_gadget_disconnect(udc->gadget); ./drivers/usb/gadget/udc/udc-core.c:502: usb_gadget_disconnect(udc->gadget); ./drivers/usb/gadget/udc/udc-core.c:673: usb_gadget_disconnect(udc->gadget); ./drivers/usb/gadget/composite.c:974: * Drivers must call usb_gadget_disconnect before calling this function ./drivers/usb/gadget/composite.c:2296: * the host, unless one of its components invokes usb_gadget_disconnect() -- Best Regards, Peter Chen -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
