| * ehci-hcd: preserve DTC in QH for interrupt transactionsAleksey Kuleshov2016-03-101-11/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | In Linux ehci-q Data Toggle Control bit for interrupt transactions is preserved in Queue Head (EHCI 3.6.2). So don't set 14's bit in qh_endpt1 and don't manage toggle bit anywhere in int transactions. This fixes an idle issue for USB keyboards, where keys were physically changed but barebox haven't seen them in polling until the next USB keyboard polling occurs.

* usb: ehci-hcd: Use regular mdelay()Sascha Hauer2015-10-141-1/+3

* usb: ehci: prevent bad PORTSC register accessKuo-Jung Su2015-08-261-6/+15
| | | | | | | | | | | | | | | | | 1. The 'index' of ehci_submit_root() is not always > 0. e.g. While it gets invoked from usb_get_descriptor(), the 'index' is always a '0'. (See ch.9 of USB2.0) 2. The PORTSC register is not always required, and thus it should only report a port error when necessary. It would cause a port scan failure if the ehci_submit_root() always gets terminated by a port error.

This fixes endianess issues for .device.bcdUSB, .device.bcdDevice, .config.wTotalLength, and .endpoint.wMaxPacketSize. Also, .endpoint.bInterval was set to 0 instead of 255 due to a copy-and-paste error while assigning u8[] to usb_endpoint_descriptor.
