Quoting from patch 8/9:

"
+==============================
+User-Space EC Interface (cdev)
+==============================
+
+The ``surface_aggregator_cdev`` module provides a misc-device for the SSAM
+controller to allow for a (more or less) direct connection from user-space to
+the SAM EC. It is intended to be used for development and debugging, and
+therefore should not be used or relied upon in any other way. Note that this
+module is not loaded automatically, but instead must be loaded manually.
"

If I'm not mistaken that seems to be pretty much what Greg asked for.

Regards,

Hans
