[PATCH] USB: ehci power fixes
Miscellaneous updates for EHCI.
- Mostly updates the power switching on EHCI controllers. One routine
centralizes the "power on/off all ports" logic, and the capability to
do that is reported more correctly.
- Courtesy Colin Leroy, a patch to always power up ports after resumes
which didn't keep a USB device suspended. The reset-everything logic
powers down those ports (on some hardware) so something needs to turn
them back on.
- Minor tweaks/bugfixes for the debug port support.
