2012-04-05dmaengine/dma_slave: introduce inline wrappersAlexandre Bounine
Add inline wrappers for device_prep_slave_sg() and device_prep_dma_cyclic() interfaces to hide new parameter from current users of affected interfaces. Convert current users to use new wrappers instead of direct calls. Suggested by Russell King [https://lkml.org/lkml/2012/2/3/269].

2011-07-01usb: gadget: allow multiple gadgets to be builtFelipe Balbi
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 Siewior
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 Morimoto
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 Morimoto
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.

2011-06-07usb: renesas_usbhs: modify data transfer methodKuninori Morimoto
On current driver, main data transfer function was implemented in fifo.c, but the overall controlling was implementing in mod_gadget.c. This style is not useful to support host and DMAEngine in the future. But the interrupt for data transfer cannot separate easily for now, because it is deeply related to mod_gadget.

2011-06-07usb: renesas_usbhs: modify packet queue control methodKuninori Morimoto
Current renesas_usbhs driver is controlling packet queue on mod_gadget.c. But it has relationship with pipe/fifo, not host/gadget.

2011-06-07usb: renesas_usbhs: divide data transfer functionsKuninori Morimoto
DMAEngine will be supported to this driver in the future. Then, both PIO and DMA data transfer method should be supported. But, the transfer function can returns the result immediately in PIO version, but it can't in DMA version.

2011-04-29usb: renesas_usbhs: add autonomy modeKuninori Morimoto
Current renesas_usbhs was designed to save power when USB is not connected. And it assumed platform uses callback to notify connection/disconnection by external interrupt.

2011-04-29usb: renesas_usbhs: don't re-allocation pipe bufferKuninori Morimoto
Because pipe buffer allocation is very picky and difficult, current renesas_usbhs driver is not caring pipe re-allocation. In this situation, driver will create new pipe without caring old pipe if "usbhsg_ep_enable" is called after "usbhsg_ep_disable" on current driver. This mean the limited pipe and buffer will be used as waste. But it is possible to re-use same buffer to same pipe. By this patch, driver will initialize pipe when it detected new connection or new gadget, and doesn't try re-allocation for same pipe in above case.
