2015-01-30usb: dwc2: gadget: fix phy interface configurationMian Yousaf Kaukab1-3/+7
hsotg->phyif is set in dwc2_gadget_init according to phy interface width. Use it for configuration instead of hardcoded value. Moreover, set USB turnaround time according to phy width.

2015-01-30usb: dwc2: gadget: don't modify pullup status during resetGregory Herrero1-1/+0
Pullup doesn't need to be enabled during usb reset since it is already enabled. This leads to shorter chirp-k duration if done during usb reset.

2015-01-30usb: dwc2: gadget: add reset flag in init functionGregory Herrero3-15/+26
Add a flag to request physical reset of the controller when s3c_hsotg_core_init_disconnected is called. During the usb reset, controller must not be fully reconfigured and resetted. Else this leads to shorter chirp-k duration during enumeration.

The omap musb front-end calls into the phy driver directly instead of using a generic phy interface, which causes a link error when the specific driver is not built-in: drivers/built-in.o: In function `omap2430_musb_disable': usb/musb/omap2430.c:480: undefined reference to `omap_control_usb_set_mode' drivers/built-in.o: In function `omap2430_musb_enable': usb/musb/omap2430.c:466: undefined reference to `omap_control_usb_set_mode' usb/musb/omap2430.c:447: undefined reference to `omap_control_usb_set_mode' drivers/built-in.o: In function `omap_musb_set_mailbox': usb/musb/omap2430.c:273: undefined reference to `omap_control_usb_set_mode' usb/musb/omap2430.c:304: undefined reference to `omap_control_usb_set_mode' drivers/built-in.o:(.debug_addr+0xbd9e0): more undefined references to `omap_control_usb_set_mode' follow This adds an explicit dependency.
