Subject: [PATCH v3 1/6] dt-bindings: clock: Add YAML schemas for the QCOM GPUCC clock bindings
Date: Fri, 27 Dec 2019 12:08:29 +0530
Message-ID: <1577428714-17766-2-git-send-email-tdas@codeaurora.org> (raw)
In-Reply-To: <1577428714-17766-1-git-send-email-tdas@codeaurora.org>

The GPUCC clock provider have a bunch of generic properties that
are needed in a device tree. Add a YAML schemas for those.

-Qualcomm Graphics Clock & Reset Controller Binding
---------------------------------------------------
-
-Required properties :
-- compatible : shall contain "qcom,sdm845-gpucc" or "qcom,msm8998-gpucc"
-- reg : shall contain base register location and length
-- #clock-cells : from common clock binding, shall contain 1
-- #reset-cells : from common reset binding, shall contain 1
-- #power-domain-cells : from generic power domain binding, shall contain 1
-- clocks : shall contain the XO clock
-	   shall contain the gpll0 out main clock (msm8998)
-- clock-names : shall be "xo"
-		shall be "gpll0" (msm8998)
-
-Example:
-	gpucc: clock-controller@5090000 {
-		compatible = "qcom,sdm845-gpucc";
-		reg = <0x5090000 0x9000>;
-		#clock-cells = <1>;
-		#reset-cells = <1>;
-		#power-domain-cells = <1>;
-		clocks = <&rpmhcc RPMH_CXO_CLK>;
-		clock-names = "xo";
