    [PATCH] USB: ehci power fixes · 56c1e26d
    David Brownell 提交于
    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.
