* usb: dwc2: retry NAK'd interrupt transfersStephen Warren2015-04-14-6/+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 Warren2015-04-14-3/+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.

* usb: dwc2: correctly program hcchar for LS devicesStephen Warren2015-04-14-9/+12
| | | | | | | | A bit must be set in HCCHAR when communicating with low-speed devices. I have no idea why there's no corresponding bit to distinguish between full-speed and high-speed devices, but no matter; they all work now! Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

* usb: dwc2: fix bulk transfersStephen Warren2015-04-14-9/+13
| | | | | | | | | | | | | | | | When I created wait_for_chhltd(), I noticed that some instances of the code it replaced expected the ACK bit to be set and others didn't. I assumed this was an accidental inconsistency in the code, so wrote wait_for_chhltd() to always expect ACK to be set. This code appeared to work correctly for both enumeration of USB keyboards and operation of USB Ethernet devices. However, this change broke USB Mass Storage (at least my USB SD card reader). This change reverts to exactly the original behaviour. I'm not sure why the ACK bit isn't always set (perhaps a quirk in the USB HW or DWC2 controller), but the code works this way!

* usb: dwc2: remove restriction on buffer lengthStephen Warren2015-04-14-9/+3
| | | | | | | | | | Each USB transfer is split up into chunks that are held in an aligned buffer. This imposes a limit on the size of each chunk, but no limit on the total size of transferred data. Fix the logic in chunk_msg() not to reject large transfers, but simply take the size of the aligned buffer into account when calculating the chunk size. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
* usb: dwc2: fix aligned buffer usageStephen Warren2015-04-14-6/+8
| | | | | | | | | | | | | | | The original aligned_buffer usage: a) Uselessly copied data into the aligned buffer even for IN transactions. Fix this my making the copy conditional. b) Always programmed the HW to transfer to/from the start of the aligned buffer. This worked fine for OUT transactions since the memcpy copied the OUT data to this location too. However, for large IN transactions, since the copy from the aligned buffer to the "client" buffer was deferred until after all chunks were transferred. it resulted in each chunk's transfer over-writing the data for the first transfer. Fix this by copying IN data as soon as it's received. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | usb_phy_enable should return status bit, but not phy mode bit, thus add a new function usb_phy_mode to query the PHY for it's mode and make usb_phy_enable just return 0 but not 'phy_ctrl & USBPHY_CTRL_OTG_ID'. Include a new board weak function board_usb_phy_mode. If board code does not reimplement this function, it just call usb_phy_mode and return usb_phy_mode's return value. The reason to include such a weak function is: " SOC OTG core <--connect--> board HOST port, but no pin id for the board host port, so board can not use usb_phy_mode to return the phy mode, but define it's own rule."
