2014-11-18usb: gadget: Add UDC driver for Broadcom USB3.0 device controller IP BDCAshwini Pahuja
This patch adds a UDC driver for Broadcom's USB3.0 Peripheral core named BDC. BDC supports control traffic on ep0 and bulk/Int/Isoch traffic on all other endpoints.

2014-11-14usb: dwc2: Update Kconfig to support dual-roleDinh Nguyen
Update DWC2 kconfig and makefile to support dual-role mode. 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.

2014-11-14usb: dwc2: move usb_disabled() call to host driver onlyDinh Nguyen
Since platform.c will get built for both Host and Gadget, if we leave the usb_disabled() call in platform.c, it results in the following build error when (!USB && USB_GADGET) condition is met. ERROR: "usb_disabled" [drivers/usb/dwc2/dwc2_platform.ko] undefined! Since usb_disabled() is mostly used to disable USB host functionality, move the call the host portion for the DWC2 driver.

2014-11-14usb: dwc2: gadget: Do not fail probe if there isn't a clock nodeDinh Nguyen
Since the dwc2 hcd driver is currently not looking for a clock node during init, we should not completely fail if there isn't a clock provided. By assigning clk = NULL, this allows the driver, when configured for dual-role mode, to be able to continue loading the host portion of the driver when a clock node is not specified.

2014-11-14usb: dwc2: Update common interrupt handler to call gadget interrupt handlerDinh Nguyen
Make dwc2_handle_common_intr call the gadget interrupt function when operating in peripheral mode. Remove the spinlock functions in s3c_hsotg_irq as dwc2_handle_common_intr() already has the spinlocks. Move the registeration of the IRQ to common code for platform and PCI. Remove duplicate interrupt conditions that was in gadget, as those are handled by dwc2 common interrupt handler.

2014-11-14usb: dwc2: Move gadget probe function into platform codeDinh Nguyen
This patch will aggregate the probing of gadget/hcd driver into platform.c. The gadget probe funtion is converted into gadget_init that is now only responsible for gadget only initialization. All the gadget resources are now handled by platform.c Since the host workqueue will not get initialized if the driver is configured for peripheral mode only. Thus we need to check for wq_otg before calling queue_work(). Also, we move spin_lock_init to common location for both host and gadget that is either in platform.c or pci.c. We also move suspend/resume code to common platform code. Lastly, move the "samsung,s3c6400-hsotg" binding into dwc2_of_match_table.

2014-11-14usb: dwc2: Update the gadget driver to use common dwc2_hsotg structureDinh Nguyen
Adds the gadget data structure and appropriate data structure pointers to the common dwc2_hsotg data structure. To keep the driver data dereference code looking clean, the gadget variable declares are only available for peripheral and dual-role mode. This is needed so that the dwc2_hsotg data structure can be used by the hcd and gadget drivers. Updates gadget.c to use the dwc2_hsotg data structure and gadget pointers that have been moved into the common dwc2_hsotg structure.

Hcd controller needs bus_suspend/resume, dwc2 controller make root hub generate suspend/resume signal with hprt0 register when work in host mode. After the root hub enter suspend, we can make controller enter low power state with PCGCTL register. We also update the lx_state for hsotg state. This patch has tested on rk3288 with suspend/resume.

commit e47d925 (usb: move the OTG state from the USB PHY to the OTG structure) moved the OTG state from struct usb_phy to struct usb_otg. Unfortunately, even though I fixed quite a few build regressions with that patch already, this one was still missing. Note that this driver still has other randconfig build problems which I'll leave for driver author to fix, as that's less trivial.

2014-11-10usb: gadget: dbgp: Fix endpoint config after USB disconnectKyösti Mälkki
SET_FEATURE request with DEBUG_MODE only worked the first time after module initialisation. Per the USB 2.0 debug device specification, said request is to be treated as if it were a SET_CONFIGURATION request, i.e. endpoint must be re-configured. As configure_endpoints() may now get called multiple times, move it outside __init and move serial_alloc_tty() call into __init. Code has assumption that endpoint mapping remains unchanged with consecutive calls of configure_endpoints().
