current mod_gadget had got usb speed on usbhsg_irq_dev_state() which is status change interrupt callback function. And the usb speed data was included in its parameter. But this style works for mod_gadget, but doesn't work for mod_host which isn't interrupted when device status was changed. This patch add usbhs_bus_get_speed() to solve this issue.

2011-07-02usb: gadget: allow multiple gadgets to be builtFelipe Balbi1-16/+0
now that we have the udc class, we can allow multiple gadget controller drivers to be compiled as modules. This will allow for distro-like kernels for embedded devices. With this patch, I managed to build an x86 kernel with support for many of the controllers enabled: CONFIG_USB_FUSB300=m CONFIG_USB_R8A66597=m CONFIG_USB_M66592=m CONFIG_USB_AMD5536UDC=m CONFIG_USB_CI13XXX_PCI=m CONFIG_USB_NET2272=m CONFIG_USB_NET2280=m CONFIG_USB_GOKU=m CONFIG_USB_LANGWELL=m CONFIG_USB_EG20T=m Also an ARM kernel with support for many controllers: CONFIG_USB_FUSB300=m CONFIG_USB_OMAP=m CONFIG_USB_R8A66597=m CONFIG_USB_GADGET_MUSB_HDRC=m CONFIG_USB_M66592=m CONFIG_USB_NET2272=m CONFIG_USB_DUMMY_HCD=m The next step would be to get rid of the direct access to arch/ and mach/ directories on some gadget controllers so that we can build all of them without depending on their respective ARCH_* symbols.

2011-06-28usb: gadget: convert all users to the new udc infrastructureSebastian Andrzej Siewior1-5/+15
peripheral drivers are using usb_add_gadget()/usb_del_gadget() to register/unregister to the udc-core. The udc-core will take the first available gadget driver and attach function driver which is calling usb_gadget_register_driver(). This is the same behaviour we have right now. Only dummy_hcd was tested, the others were compiled tested.

2011-06-07usb: renesas_usbhs: add DMAEngine supportKuninori Morimoto7-3/+516
USB DMA was installed on "normal DMAC" when SH7724 or older SuperH, but the "USB-DMAC" was prepared on recent SuperH. These 2 DMAC have a little bit different behavior. This patch add DMAEngine code for "normal DMAC", but it is still using PIO fifo. The DMA fifo will be formally supported in the future. You can enable DMA fifo by local fixup usbhs_fifo_pio_push_handler -> usbhs_fifo_dma_push_handler usbhs_fifo_pio_pop_handler -> usbhs_fifo_dma_pop_handler on usbhsg_ep_enable.

packet transfer timing are controlled in mod_gadget on current renesas_usbhs, and this style will be imitated on mod_host. But it need not be managed with host/gadget if it is general transfer.

2011-06-07usb: renesas_usbhs: add pipe/fifo linkKuninori Morimoto4-12/+55
renesas_usbhs has CFIFO which is for PIO transfer, and D0FIFO/D1FIFO which are for DMA transfer. The pipe selects one of these fifo when it send/recv data. But fifo must not be selected to different pipe in same time. This patch add pipe/fifo link for each other, and fifo is not selected by another pipe until it is unselected.
