* Qualcomm Technologies, Inc. MSM Camera IFE CSID

Camera IFE CSID device provides the definitions for enabling
the IFE CSID hardware. It also provides the functions for the client
to control the IFE CSID hardware.

=======================
Required Node Structure
=======================
The IFE CSID device is described in one level of the device node.
