* Qualcomm Technologies, Inc. MSM Camera TFE CSID
|
|
|
|
Camera TFE CSID device provides the definitions for enabling
|
|
the TFE CSID hardware. It also provides the functions for the client
|
|
to control the TFE CSID hardware.
|
|
|
|
=======================
|
|
Required Node Structure
|
|
=======================
|
|
The TFE CSID device is described in one level of the device node.
