2011-10-13usb: gadget: renesas_usbhs: add usbhs_bus_get_speed()Kuninori Morimoto5-19/+18
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.

2011-10-13usb: gadget: renesas_usbhs: each pipe hold maxpacket sizeKuninori Morimoto2-21/+10
Current renesas_usbhs pipe accessed DCPMAXP/PIPEMAXP register to get own maxpacket size every time. But maxpacket size isn't changed after pipe start, and register access is too slow. This patch adds new maxp variable to keep own maxpacket. And un-used function are removed. Signed-off-by: Kuninori Morimoto <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>

2011-07-01usb: 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.

2011-06-07usb: renesas_usbhs: tifyup packet start timingKuninori Morimoto2-17/+11
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. By this patch, the packet transfer timing is managed in fifo.c Signed-off-by: Kuninori Morimoto <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
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.

2011-06-07usb: renesas_usbhs: add usbhsf_fifoKuninori Morimoto4-24/+77
renesas_usbhs has CFIFO/D0FIFO/D1FIFO. But current renesas_usbhs is using CFIFO (for PIO) only for now. The fifo selection method is needed for DMAEngine support.

2011-06-07usb: renesas_usbhs: modify data transfer interruptKuninori Morimoto5-294/+204
On current driver, overall data transfer method was implemented in fifo.c, but its interrupt which is member of packet queue control was still in mod_gadget.c. This patch move it into fifo.c. By this patch, the packet/fifo control is independent from mod_gadget. Signed-off-by: Kuninori Morimoto <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2011-06-07usb: renesas_usbhs: modify data transfer methodKuninori Morimoto3-163/+148
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. This patch move the overall data transfer method into fifo.c except interrupt. Signed-off-by: Kuninori Morimoto <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2011-06-07usb: renesas_usbhs: modify packet queue control methodKuninori Morimoto5-24/+53
Current renesas_usbhs driver is controlling packet queue on mod_gadget.c. But it has relationship with pipe/fifo, not host/gadget. So, controlling USB packet queue in pipe.c/fifo.c is more convenient than in mod_gadget.c. This patch modify it.

2011-06-07usb: renesas_usbhs: divide data transfer functionsKuninori Morimoto6-60/+150
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. This patch divides data transfer functions into top/bottom half in preparation for DMAEngine support.

2011-06-07usb: renesas_usbhs: fifo became independent from pipe.Kuninori Morimoto7-251/+290

Current driver had pipe direction flag which came from usb_endpoint_dir_in(). It means "input direction" for HOST, and "out direction" for Gadget. But driver needs "input direction for pipe".

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.
