[PATCH] USB: Add isp116x-hcd USB host controller driver
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.
