Merge branch 'for-linus-3.6' of git://dev.laptop.org/users/dilinger/linux-olpc
Pull OLPC platform updates from Andres Salomon:
"These move the OLPC Embedded Controller driver out of
arch/x86/platform and into drivers/platform/olpc.
OLPC machines are now ARM-based (which means lots of x86 and ARM
changes), but are typically pretty self-contained.. so it makes more
sense to go through a separate OLPC tree after getting the appropriate
review/ACKs."
* 'for-linus-3.6' of git://dev.laptop.org/users/dilinger/linux-olpc:
x86: OLPC: move s/r-related EC cmds to EC driver
Platform: OLPC: move global variables into priv struct
Platform: OLPC: move debugfs support from x86 EC driver
x86: OLPC: switch over to using new EC driver on x86
Platform: OLPC: add a suspended flag to the EC driver
Platform: OLPC: turn EC driver into a platform_driver
Platform: OLPC: allow EC cmd to be overridden, and create a workqueue to call it
drivers: OLPC: update various drivers to include olpc-ec.h
Platform: OLPC: add a stub to drivers/platform/ for the OLPC EC driver
