* 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.
======================================
First Level Node - CAM IFE CSID device

Definition: Regulator reference corresponding to the names listed in
"regulator-names".
- clock-names
Usage: required
Value type: <string>
Definition: List of clock names required for IFE CSID HW.
- clocks
Usage: required
Value type: <phandle>
Definition: List of clocks used for IFE CSID HW.
- clock-rates
Usage: required
Value type: <u32>
Definition: List of clocks rates.
- clock-cntl-level
Usage: required
Value type: <string>
Definition: All different clock level node can support.
- src-clock-name
Usage: required
