[PATCH 1/1] dt-bindings: cpufreq-dt: Remove redundant cpufreq-dt.txt

[Frank Li]

The information is already documented in
Documentation/devicetree/bindings/arm/cpus.yaml.
Documentation/devicetree/bindings/opp/opp-v1.yaml

Remove the redundant file.

-Generic cpufreq driver
-
-It is a generic DT based cpufreq driver for frequency management.  It supports
-both uniprocessor (UP) and symmetric multiprocessor (SMP) systems which share
-clock and voltage across all CPUs.
-
-Both required and optional properties listed below must be defined
-under node /cpus/cpu@0.
-
-Required properties:
-- None
-
-Optional properties:
-- operating-points: Refer to Documentation/devicetree/bindings/opp/opp-v1.yaml for
-  details. OPPs *must* be supplied either via DT, i.e. this property, or
-  populated at runtime.
-- clock-latency: Specify the possible maximum transition latency for clock,
-  in unit of nanoseconds.
-- voltage-tolerance: Specify the CPU voltage tolerance in percentage.
-- #cooling-cells:
-     Please refer to
-     Documentation/devicetree/bindings/thermal/thermal-cooling-devices.yaml.
-
-Examples:
-
-cpus {
-	#address-cells = <1>;
-	#size-cells = <0>;
-
-	cpu@0 {
-		compatible = "arm,cortex-a9";
-		reg = <0>;
-		next-level-cache = <&L2>;
-		operating-points = <
-			/* kHz    uV */
-			792000  1100000
-			396000  950000
-			198000  850000
-		>;
-		clock-latency = <61036>; /* two CLK32 periods */
-		#cooling-cells = <2>;
-	};
-
-	cpu@1 {
-		compatible = "arm,cortex-a9";
-		reg = <1>;
-		next-level-cache = <&L2>;
-	};
-
-	cpu@2 {
-		compatible = "arm,cortex-a9";
-		reg = <2>;
-		next-level-cache = <&L2>;
-	};
-
-	cpu@3 {
-		compatible = "arm,cortex-a9";
-		reg = <3>;
-		next-level-cache = <&L2>;
-	};

Even then, we can document what driver expects. So duplication isn't
an issue I think.

But this file is outdated and hasn't received an update in years.

Merged with this commit log instead.

    dt-bindings: Remove outdated cpufreq-dt.txt

    The information present in this file is outdated and doesn't serve any
    purpose with the current design of the driver.

    Remove the outdated file.
