Revision 85f90cf6ca569b19cee212844b543a7355b77163 authored by Andres Salomon on 13 July 2012, 00:57:28 UTC, committed by Andres Salomon on 01 August 2012, 03:27:30 UTC
This uses the new EC driver framework in drivers/platform/olpc. The XO-1 and XO-1.5-specific code is still in arch/x86, but the generic stuff (including a new workqueue; no more running EC commands with IRQs disabled!) can be shared with other architectures.
