usb: dwc2: disable erroneous overcurrent condition

2016-03-05T01:21:36+00:00

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: ehci: Be explicit about the BE IO accessors

2016-02-24T18:12:32+00:00

Add explicit cpu_to_be32()/be32_to_cpu() conversion to BE EHCI I/O
accessors to align them with their LE counterpart. No functional

usb: ehci: Implement V2P mapping

2016-02-24T18:12:32+00:00

Certain processor architectures, like MIPS, require that the USB
structures and transfer buffers are passed with their PA to the
USB controller. If VA is passed, the USB will not work. Add the
necessary virt_to_phys() calls into the USB EHCI code to make it
work.
