* 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: dwc2: Do not mix data toggle for IN and OUT endpoints, check boundsStefan Brüns2016-01-23-10/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * usb: dwc2: Add SPLIT INTERRUPT transaction supportStefan Brüns2016-01-23-5/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: dwc2: Implement SPLIT transaction supportStefan Brüns2016-01-23-15/+66
| | | | | | | | | | | | | | | | | | In contrast to non-SPLIT transfers each transaction has to be submitted as an individual chunk. The transaction state machine proceeds from SSPLIT to CSPLIT if the ACK flag is set. CSPLIT has to be repeated while NYET is set. Signed-off-by: Stefan Brüns <stefan.bruens@rwth-aachen.de>

| | | | | | | | | | | | | | | | | | | | | | | | A transfer is completed if the XFERCOMP flag is set, irrespective of the ACK flag. BULK OUT transfers to some HS devices complete without having the ACK flag set, which signal the devices has responded with an NYET to the transfer (PING protocol).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix two errors in transfer len calculation, move loop invariant code out of loop. If xfer_len is equal to CONFIG_DWC2_MAX_TRANSFER_SIZE (or slightly smaller), the xfer_len will be to large, e.g.: xfer_len = MAX_TRANSFER_SIZE = 65535 max packet size = 512 => num_packets = 128 => IN xfer_len = 65536 For OUT transactions larger than (65536 - mps) bytes, the xfer_len determination is quite awkward, it is only correct due to: - max_packet_size for control/bulk/interrupt is required to be power-of-two. - (CONFIG_DWC2_MAX_TRANSFER_SIZE + 1) % max-packet-size is zero for all allowed (2^3 ... 2^9) packet sizes As the max xfer len is loop invariant, it can be moved out of the loop.

| | | | | | | | | | | | | With the old order of initialization the hcor pointer has been setup to the same address as Exynos EHCI base address (0x12110000 instead of 0x12110010).
