From 56c1e26d75008d39f1067f453719857a81109d9f Mon Sep 17 00:00:00 2001 From: David Brownell Date: Sat, 9 Apr 2005 09:00:29 -0700 Subject: [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.
