* usb: dwc2: disable erroneous overcurrent conditionDinh Nguyen2016-03-05-1/+5
| | | | | | | | | | | For the case where an external VBUS is used, we should enable the external VBUS comparator in the driver. This would prevent an unnecessary overcurrent error which would then disable the host port. The overcurrent condition was happening on the SoCFPGA Cyclone5 devkit, thus USB was not working on the devkit. This patch fixes that problem.

* usb: gadget: composite: Correct recovery path for registerSam Protsenko2016-03-01-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | In case when usb_composite_register() failed once (for whatever reason), it will fail further even if all conditions are correct. Example: => fastboot 2 Invalid Controller Index couldn't find an available UDC g_dnl_register: failed!, error: -19 exit not allowed from main input shell. => fastboot 0 g_dnl_register: failed!, error: -22 exit not allowed from main input shell. Despite that 0 is correct index for USB controller, "fastboot 0" command will fail, because "composite" structure wasn't cleared properly on previous fail (on "fastboot 2" command). This patch fixes that erroneous behavior, allowing us to use composite even after previous failure. Signed-off-by: Sam Protsenko <semen.protsenko@linaro.org>

* dfu: usb: f_dfu: Set deferred call for dfu_flush() functionLukasz Majewski2016-02-24-8/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes situation when one would like to write large file into medium with the file system (fat, ext4, etc). This change sets file size limitation to the DFU internal buffer size. Since u-boot is not supporting interrupts and seek on file systems, it becomes challenging to store large file appropriately. To reproduce this error - create large file (around 26 MiB) and sent it to the target board. Lets examine the flow of USB transactions: 0. DFU uses EP0 with 64B MPS [Max Packet Size] 1. Send file - OUT (PC->target) - dat_26MiB.img is sent with 4096 B transactions 2. Get status - OUT (PC->target) - wait for DFU_STATE_dfuDNLOAD_IDLE (0x05) sent from target board - IN transaction (target->PC) 3. The whole file content is sent to target - OUT (PC->target) with ZLP [Zero Length Packet] Now the interesting part starts: 4. OUT (PC->target) Setup transaction (request to share DFU state) 5. IN (target->PC) - reply the current DFU state - In the UDC driver the req->completion (with dfu_flush) is called after successful IN transfer. - The dfu_flush() (called from req->completion callback) saves the whole file at once (u-boot doesn't support seek on fs). Such operation takes considerable time. When the file is large - e.g. 26MiB - this time may be more than 5 seconds. 6. OUT (PC->target) - ZLP, is send in the same time when dfu_flush() writes data to eMMC memory. The dfu-util application has hard coded timeout on USB transaction completion set to 5 seconds (it uses libusb calls). When the file to store is large (e.g. 26 MiB) the time needed to write it may excess the dfu-util timeout and following error message will be displayed: "unable to read DFU status" on the HOST PC console. This change is supposed to leverage DFU's part responsible for storing files on file systems. Other DFU operations - i.e. raw/partition write to NAND and eMMC should work as before. The only functional change is the error reporting. When dfu_flush() fails the u-boot prompt will exit with error information and dfu-util application exits afterwards as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | USB protocol allows for 16 IN and 16 OUT endpoints (USB 2.0 Spec, 8.3.2.2 Endpoint Field). A function may have an EP 1 for both IN and OUT, so these two should be kept separate. As EPs are either BULK or INTERRUPT (or ISO), it is fine to have one array per direction for all transfer types (also see e236519b7365ef75c5da6a5623f0b03d9c00cfae). USB device address is 7 bits, so a bus may have more than 16 devices. Check the device number, as the DWC2 driver only supports BULK/ISO for the first 16 devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | CSPLITs for INTERRUPT transactions have to be scheduled in each microframe following the SSPLIT. INTERRUPT transfers are executed in the next even/ odd microframe depending on the HCCHAR_ODDFRM flag. As there are no handshakes for INTERRUPT SSPLITs the SSPLIT may have failed (transport error) without the error being detected by the host driver. If the last CSPLIT is not received within 4 microframes after the SSPLIT there was a transaction error and the complete transaction has to be restarted.

* usb: musb: Fix hub port setting for SPLIT transactionsStefan Brüns2015-12-31-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | The ifdef'ed Linux kernel code uses the 1 based port number, whereas U-Boot puts a 0 based port number into the register. The reason the 0 based port number apparently works can probably be taken from the USB 2.0 spec: 8.4.2.2 Start-Split Transaction Token ... The host must correctly set the port field for single and multiple TT hub implementations. A single TT hub implementation *may ignore* the port field. Actually, as far as I understand, a multi TT hub defaults to single TT (bAlternateSetting: 0) until switched via SetInterface, so even "port 42" would work. The change was verified by hardcoding the port number to a wrong value, SPLIT transactions kept working (although using a DWC2 instead of MUSB). Tested hubs are the RPi onboard SMC9514 and an external "05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB". The former is a multi TT hub, the latter single TT only.
