* Qualcomm Technologies, Inc. MSM Camera LRME
|
|
|
|
The MSM camera Low Resolution Motion Estimation device provides dependency
|
|
definitions for enabling Camera LRME HW. MSM camera LRME is implemented in
|
|
multiple device nodes. The root LRME device node has properties defined to
|
|
hint the driver about the LRME HW nodes available during the probe sequence.
|
|
Each node has multiple properties defined for interrupts, clocks and
|
|
regulators.
|
|
|
|
=======================
|
|
Required Node Structure
|
|
=======================
|
|
LRME root interface node takes care of the handling LRME high level
|
|
driver handling and controls underlying LRME hardware present.
