-Qualcomm OPP bindings to describe OPP nodes
-
-The bindings are based on top of the operating-points-v2 bindings
-described in Documentation/devicetree/bindings/opp/opp-v2-base.yaml
-Additional properties are described below.
-
-* OPP Table Node
-
-Required properties:
-- compatible: Allow OPPs to express their compatibility. It should be:
-  "operating-points-v2-qcom-level"
-
-* OPP Node
-
-Required properties:
-- qcom,opp-fuse-level: A positive value representing the fuse corner/level
-  associated with this OPP node. Sometimes several corners/levels shares
-  a certain fuse corner/level. A fuse corner/level contains e.g. ref uV,
-  min uV, and max uV.
