[RFC PATCH 1/3] dt-bindings: media: qcom: Add CAMSS Offline Processing Engine (OPE)

[Loic Poulain]

Add Devicetree binding documentation for the Qualcomm Camera Subsystem
Offline Processing Engine (OPE) found on platforms such as Agatti.
The OPE is a memory-to-memory image processing block which operates
on frames read from and written back to system memory.

+description:
+  The Qualcomm Camera Subsystem (CAMSS) Offline Processing Engine (OPE)
+  is a memory-to-memory image processing block used. It supports a
+  range of pixel-processing operations such as scaling, cropping, gain
+  adjustments, white-balancing, and various format conversions. The OPE
+  does not interface directly with image sensors, instead, it processes
+  frames sourced from and written back to system memory.
