Any comments on this series? The last version was posted a couple of weeks
ago but the series have been in the list for months. Lee has already acked
the mfd changes so you can merge all through your chrome-platform tree if
you want.

It wold be great if this series get in to have the EC user-space interface
supported and to minimize the delta with the Chromemium OS kernel since it
still has other features that needs to be upstreamed like multiple EC in a
system and access to vboot context stored in block device or EC's nvram.
