From ac9a9cd2cbbe20629ef08d21caeecb099035e109 Mon Sep 17 00:00:00 2001 From: "Mike J. Chen" Date: Sat, 11 Sep 2010 22:16:37 -0700 Subject: S5PC11X: SENSOR: Add libsensor HAL. Goes with kernel drivers. Modeled after NexusOne version that uses input framework. We removed the old device nodes and add rules to make the new sysfs attributes accessible with the right permissions. Change-Id: I61e12da6c553eee664cebee9b9b9a77f9d099020 Signed-off-by: Mike J.
