* usb: gadget: add "maxpacket_limit" field to struct usb_epRobert Baldyga2013-12-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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.

Here's what it contains: For am5536udc we have just simple coding style fixes. Nothing that has any potential to cause any issues going forward. With mv_udc, there's only one single change removing an unneeded NULL check. at91_udc also only saw a single change this merge window, and that's only removing a duplicated header. The Renesas controller has a few more involved changes. Support for SUDMAC was added, there's now a special handling of IRQ resources for when the IRQ line is shared between Renesas controller and SUDMAC, we also had a bug fix where Renesas controller would sleep in atomic context while doing DMA transfers from a tasklet. There were also a set of minor cleanups. The FSL UDC also had a scheduling in atomic context bug fix, but that's all. Thanks to Sebastian, the dummy_hcd now works better than ever with support for scatterlists and streams. Sebastian also added SuperSpeed descriptors to the serial gadgets. The highlight on this merge is the addition of a generic API for mapping and unmapping usb_requests. This will avoid code duplication on all UDC controllers and also kills all the defines for DMA_ADDR_INVALID which UDC controllers sprinkled around. A few of the UDC controllers were already converted to use this new API. Conflicts: drivers/usb/dwc3/gadget.c

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.

| * usb: udc: Fix gadget driver's speed check in various UDC driversMichal Nazarewicz2011-11-291-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several UDC drivers had a gadget driver's speed sanity check of the form of: driver->speed != USB_SPEED_HIGH or: driver->speed != USB_SPEED_HIGH && driver->speed != USB_SPEED_FULL As more and more gadget drivers support USB SuperSpeed, driver->speed may be set to USB_SPEED_SUPER and UDC driver should handle such gadget correctly. The above checks however fail to recognise USB_SPEED_SUPER as a valid speed. This commit changes the two checks to: driver->speed < USB_SPEED_HIGH or: driver->speed < USB_SPEED_FULL respectively.

* | usb: convert drivers/usb/* to use module_platform_driver()Axel Lin2011-11-281-13/+2
|/ | | | | | | | | | | | | | | | | This patch converts the drivers in drivers/usb/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

* s3c-hsudc: Fix possible nullpointer dereference during probeHeiko Stübner2011-08-221-13/+13
| | | | | | | | | | | | | The usb-interrupt is requested before the endpoints are initalised. If an interrupt happens in the time between request_irq and the init of the endpoint-data (as seen on the Qisda ESx00 ebook-platforms), it is therefore possible for the interrupt handler to access endpoint- data before its creation resulting in a null-pointer dereference. This patch simply moves the irq request below the endpoint init. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
