The SpacemiT K1 SoC has two USB2.0 controllers, one has Dual-Role
support, but the hardware has no internal OTG registers, the other is
Host only. These controllers are compatible with Chipidea USB2 driver
with some flags set and reset control support.
This series is based on 7.2-rc1 and has been tested on Banana Pi F3
development board.
A self-powered USB device/hub is needed to test the host function of the
dual-role controller on Banana Pi F3, a MINI-PCIe USB2.0 module (a
cellular module e.g.) is needed to test the host only controller.
