Subject: [PATCH 08/13] dt-bindings: opp: Add qcom-opp bindings with properties needed for CPR
Date: Fri, 5 Jul 2019 11:57:19 +0200 [thread overview]
Message-ID: <20190705095726.21433-9-niklas.cassel@linaro.org> (raw)
In-Reply-To: <20190705095726.21433-1-niklas.cassel@linaro.org>
Add qcom-opp bindings with properties needed for Core Power Reduction
(CPR).
CPR is included in a great variety of Qualcomm SoCs, e.g. msm8916 and
msm8996. CPR was first introduced in msm8974.
Changes since RFC:
-Removed opp-hz. It is already an optional property in opp.txt
so no need to specify it with the same definition here.

+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.txt
+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
+
+Optional 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.
