| * usb: gadget: amd5536udc: remove unnecessary conditionsSudip Mukherjee2015-10-01
| | | | | | | | | | | | | | | | | | | | | | | | The condition checking for irq_registered, regs, mem_region and active are not required as this is the remove function. And we are in the remove means that probe was successful and they can never be NULL at this point of code. It was required in the original code as the remove function was part of the error handler of probe function.

| * usb: gadget: amd5536udc: use free_dma_poolsSudip Mukherjee2015-10-01
| | | | | | | | | | | | | | | | | | | | | | We have the function free_dma_pools() which frees all the dma pools. Use it instead of calling all the functions separately. The if conditions for data_requests and stp_requests are also not required here as this is the remove function and we are here means probe has succeeded and dma has been successfully allocated, so they cannot be NULL here.

* usb: gadget: dummy_hcd: in transfer(), return data sent, not limitIgor Kotrasinski2015-09-21
| | | | | | | | | | | | | | | dummy_timer uses transfer() to update transfer limit. However, limit passed to dummy_timer changes depending on transfer type, so the actual limit is overwritten. This can cause unpredictably slow / fast bulk transfers when coupled with control / interrupt transfers. Fix by returning actual amount of data sent in transfer() and substracting from total.

* usb: gadget: dummy_hcd: emulate sending zlp in packet logicIgor Kotrasinski2015-09-21
| | | | | | | | | | | | | | | | | | currently, when a zlp flag is set and an urb/usb_request buffer is filled without a short packet, transfer() leaves its status at -EINPROGRESS and does not rescan for short packet. In a scenario where ep.maxpacket bytes are copied, URB_ZERO_PACKET is set, urb buffer is filled and usb_request buffer is not, transfer() returns with an urb with -EINPROGRESS status, which dummy_hcd treats as incomplete transfer. Check for zlp and rescan appropriately. Signed-off-by: Igor Kotrasinski <i.kotrasinsk@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

| | | | | | | | | | | | | | The recently added endpoint capabilities flags verification breaks Atmel USBA because the endpoint configuration was only added when the driver is bound using the legacy pdata interface.

* usb: gadget: amd5536udc: fix error handling in udc_pci_probe()Alexey Khoroshilov2015-09-14
| | | | | | | | | | | | | | | | If a failure happens early in udc_pci_probe(), error handling code just kfree(dev) and returns. The patch adds proper resource deallocations in udc_pci_probe() itself, since udc_pci_remove() is not suitabe to be called so early in initialization process. By the way, iounmap(dev->regs) is replaced by iounmap(dev->virt_addr) in udc_pci_remove() for clarity. Found by Linux Driver Verification project (linuxtesting.org).

MUSB also got support for building all DMA engines in one binary; this will be great for distros. DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely on tracing to debug DWC3. There was also a fix for memory corruption with EP0 when maxpacket size transfers are > 512 bytes. Robert's EP capabilities flags is making EP selection a lot simpler. UDCs are now required to set these flags up when adding endpoints to the framework. Other than these, we have the usual set of miscelaneous cleanups and minor fixes.
