This patch provides an "isp116x-hcd" driver for Philips' ISP1160/ISP1161 USB host controllers. The driver: - is relatively small, meant for use on embedded platforms. - runs usbtests 1-14 without problems for days. - has been in use by 6-7 different people on ARM and PPC platforms, running a range of devices including USB hubs. - supports suspend/resume of both the platform device and the root hub; supports remote wakeup of the root hub (but NOT the platform device) by USB devices. - does NOT support ISO transfers (nobody has asked for them). - is PIO-only.
