commit 2868f4f0870af07129292babee3048c41be78718 Author: Stefan Reinauer reinauer@chromium.org Date: Tue Jan 7 09:53:06 2014 -0800
panther: Add ACPI code to support wake-on-lan
There needs to be an ACPI linkage to provide the power resource needed to wake this device so the kernel will enable the SCI before going to suspend.
A link is added for both NIC and WLAN, but it is only tested on the NIC.
This is a forward port from Duncan's beltino patch.
BUG=chrome-os-partner:24657 BRANCH=panther TEST=build and boot on panther, suspend and wake with etherwake
