From a980e046098b0a40eaff5e4e7fcde6cf035b7c06 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Wed, 25 Apr 2012 15:54:59 +0100 Subject: IIO: Move the core files to drivers/iio Take the core support + the kfifo buffer implentation out of staging. Whilst we are far from done in improving this subsystem it is now at a stage where the userspae interfaces (provided by the core) can be considered stable. Drivers will follow over a longer time scale.
