commit 76ef370726a095310d1657ba7871b164e7c1b2d2 Author: Duncan Laurie dlaurie@chromium.org Date: Wed May 22 09:51:11 2013 -0700
lynxpoint: Fix XHCI controller device in ACPI
The ACPI code was defining two EHCI controllers and ignoring the XHCI controller. This changes the second EHCI controller to be XHCI instead and changes the wake resource to indicate S3 and not S4.
cat /proc/acpi/wakeup
Device S-state Status Sysfs node HDEF S4 *disabled pci:0000:00:1b.0 EHCI S3 *enabled pci:0000:00:1d.0 XHCI S3 *enabled pci:0000:00:14.0
