* | usb: modify usb_gadget_handle_interrupts to take controller indexKishon Vijay Abraham I2015-04-1415-25/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we support multiple dwc3 controllers to be existent at the same time, in order to handle the interrupts of a particular dwc3 controller usb_gadget_handle_interrutps should take controller index as an argument. Hence the API of usb_gadget_handle_interrupts is modified to take controller index as an argument and made the corresponding changes to all the usb_gadget_handle_interrupts calls.

* | usb: dwc2: retry NAK'd interrupt transfersStephen Warren2015-04-141-6/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IIUC, interrupt transfers are NAK'd by devices until they wish to trigger an interrupt, and e.g. EHCI controllers retry these in HW until they are ACK'd. However, DWC2 doesn't seem to retry, so we need to do this in SW. In practice, I've seen DWC2_HCINT_FRMOVRUN happen too. I'm not quite sure what this error implies; perhaps it's related to how near the end of a USB frame we're at when the interrupt transfer is initiated? Anyway, retrying this temporary error seems to be necessary too. With all these commits applied, both my USB keyboards (one LS Lenovo and one FS Dell) work correctly when there is no USB hub between the SoC and the keyboard; We still need split transactions to be implemented for hubs to work.

* | usb: dwc2: implement interrupt transfersStephen Warren2015-04-141-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As best I can tell, there's no difference between bulk and interrupt transfers in terms of how the HW should be programmed, at least given that we're executing one transaction at a time rather than scheduling them into frames for maximum throughput. This patch ends up sharing the toggle bit state between bulk and interrupt transfers on a particular EP. However I believe this is fine; AFAIK a given EP either uses bulk or interrupt transfers and doesn't mix them. This patch doesn't do anything with the "interval" parameter for interrupt transfers, but then most other USB controller drivers in U-Boot don't either. It turns out that one of my keyboards is happy to work using control transfers but the other only gives non-zero "HID reports" via interrupt transfers.
