* 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.
