2014-07-16usb: gadget: Gadget directory cleanup - group UDC driversAndrzej Pietrasiewicz
The drivers/usb/gadget directory contains many files. Files which are related can be distributed into separate directories. This patch moves the UDC drivers into a separate directory. Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2013-12-17usb: gadget: add "maxpacket_limit" field to struct usb_epRobert Baldyga
This patch adds "maxpacket_limit" to struct usb_ep. This field contains maximum value of maxpacket supported by driver, and is set in driver probe. This value should be used by autoconfig() function, because value of field "maxpacket" is set to value from endpoint descriptor when endpoint becomes enabled. So when autoconfig() function will be called again for this endpoint, "maxpacket" value will contain wMaxPacketSize from descriptior instead of maximum packet size for this endpoint. For this reason this patch adds new field "maxpacket_limit" which contains value of maximum packet size (which defines maximum endpoint capabilities). This value is used in ep_matches() function used by autoconfig(). Value of "maxpacket_limit" should be set in UDC driver probe function, using usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function set choosen value to both "maxpacket_limit" and "maxpacket" fields. This patch modifies UDC drivers by adding support for maxpacket_limit.

2011-12-12usb: gadget: rename usb_gadget_driver::speed to max_speedMichal Nazarewicz
This commit renames the “speed” field of the usb_gadget_driver structure to “max_speed”. This is so that to make it more apparent that the field represents the maximum speed gadget driver can support. This also make the field look more like fields with the same name in usb_gadget and usb_composite_driver structures. All of those represent the *maximal* speed given entity supports. After this commit, there are the following fields in various structures: * usb_gadget::speed - the current connection speed, * usb_gadget::max_speed - maximal speed UDC supports, * usb_gadget_driver::max_speed - maximal speed gadget driver supports, and * usb_composite_driver::max_speed - maximal speed composite gadget supports.

2011-07-05usb: gadget: fusb300_udc: fix compile warningsSebastian Andrzej Siewior
- remove pointer u32 abuse in fusb300_fill_idma_prdtbl(). It is assigned the dma_addr to a pointer and then back. Poor families may have to recycle variables but we don't - don't free req.buf in error case. We don't do it in the ok case so it is probably wrong to do it in error case. - return in error case. There is no reason to continue without data and performing ops on an invalid pointer. - The if (d) statement is bogus since an invalid DMA pointer is ~0 on some architecutres. And since we return for the invalid case we don't need it. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Felipe Balbi <balbi@ti.com>
