usb: gadget: atmel_usba_udc: Expose correct device speed

2015-12-09T19:31:21Z

commit d134c48d889ddceadf4c990e6f3df16b816ed5d4 upstream. Following changes that appeared in lk 4.0.0, the gadget udc driver for some ARM based Atmel SoCs (e.g. at91sam9x5 and sama5d3 families) incorrectly deduced full-speed USB link speed even when the hardware had negotiated a high-speed link. The fix is to make sure that the UDPHS Interrupt Enable Register value does not mask the SPEED bit in the Interrupt Status Register. For a mass storage gadget this problem lead to failures when the host had a USB 3 port with the xhci_hcd driver. If the host was a USB 2 port using the ehci_hcd driver then the mass storage gadget worked (but probably at a lower speed than it should have).

usb: gadget: net2280: restore ep_cfg after defect7374 workaround

2015-12-09T19:31:20Z

commit 81e9d14a53eb1abfbe6ac828a87a2deb4702b5f1 upstream. Defect 7374 workaround enables all GPEP as endpoint 0. Restore endpoint number when defect 7374 workaround is disabled. Otherwise, check to match USB endpoint number to hardware endpoint number in net2280_enable() fails.

usb: gadget: m66592-udc: forever loop in set_feature()

2015-09-21T17:10:52Z

commit 5feb5d2003499b1094d898c010a7604d7afddc4c upstream. There is an "&&" vs "||" typo here so this loops 3000 times or if we get unlucky it could loop forever.

usb: udc: core: add device_del() call to error pathway

2015-08-03T14:54:18Z

This patch fixes a bug in the error pathway of usb_add_gadget_udc_release() in udc-core.c. If the udc registration fails, the gadget registration is not fully undone; there's a put_device(&gadget->dev) call but no device_del().

usb: gadget: bdc: fix a driver crash on disconnect

2015-07-27T15:15:06Z

ep_dequeue() in bdc_ep.c was capturing the hw dequeue pointer incorrectly by reading the wrong register for the upper 32 bits. Signed-off-by: Al Cooper Signed-off-by: Felipe Balbi

usb: gadget: udc: core: Fix argument of dma_map_single for IOMMU

2015-07-20T17:57:46Z

The dma_map_single and dma_unmap_single should set "gadget->dev.parent" instead of "&gadget->dev" in the first argument because the parent has a udc controller's device pointer. Otherwise, iommu functions are not called in ARM environment. Signed-off-by: Yoshihiro Shimoda Signed-off-by: Felipe Balbi

usb: gadget: mv_udc_core: fix phy_regs I/O memory leak

2015-07-20T17:57:46Z

There was an omission in transition to devm_xxx resource handling. iounmap(udc->phy_regs) were removed, but ioremap() was left without devm_.

usb: gadget: udc: fix free_irq() after request_irq() failed

2015-07-06T17:34:08Z

My static checker detected the mistake. I fix this by changing "goto err_irq" to "goto err_req". The label err_irq is not used now so this patch also removes it. Signed-off-by: Takeshi Yoshimura Signed-off-by: Felipe Balbi
