code in content should be in the content namespace, not any other namespace. you
can fix this file in a followup change, but all the new files that you're adding
should be in "content" namespace

 
 class CONTENT_EXPORT DeviceData :
     public base::RefCountedThreadSafe<DeviceData> {
  public:
   enum Type {
+    kTypeMotion,
     kTypeOrientation,
     kTypeTest
   };

   virtual bool ShouldFireEvent(const DeviceData* other) const = 0;

   virtual ~DeviceData() {}
