* Qualcomm Technologies, Inc. MSM Camera OPE
|
|
|
|
The ope device node has properties defined to hint the driver
|
|
about the number of OPE nodes available during the
|
|
probe sequence. Each node has multiple properties defined
|
|
for interrupts, clocks and regulators.
|
|
|
|
=======================
|
|
Required Node Structure
|
|
=======================
|
|
OPE root interface node takes care of the handling account for number
|
|
of OPE devices present on the hardware.
|
|
|
|
