-Qualcomm Technologies, Inc. CPUFREQ Bindings
-
-CPUFREQ HW is a hardware engine used by some Qualcomm Technologies, Inc. (QTI)
-SoCs to manage frequency in hardware. It is capable of controlling frequency
-for multiple clusters.
-
-Properties:
-- compatible
-	Usage:		required
-	Value type:	<string>
-	Definition:	must be "qcom,cpufreq-hw" or "qcom,cpufreq-epss".
-
-- clocks
-	Usage:		required
-	Value type:	<phandle> From common clock binding.
-	Definition:	clock handle for XO clock and GPLL0 clock.
-
-- clock-names
-	Usage:		required
-	Value type:	<string> From common clock binding.
-	Definition:	must be "xo", "alternate".
-
-- reg
-	Usage:		required
-	Value type:	<prop-encoded-array>
-	Definition:	Addresses and sizes for the memory of the HW bases in
-			each frequency domain.
-- reg-names
-	Usage:		Optional
-	Value type:	<string>
-	Definition:	Frequency domain name i.e.
-			"freq-domain0", "freq-domain1".
-
-- #freq-domain-cells:
-	Usage:		required.
-	Definition:	Number of cells in a freqency domain specifier.
-
-* Property qcom,freq-domain
-Devices supporting freq-domain must set their "qcom,freq-domain" property with
-phandle to a cpufreq_hw followed by the Domain ID(0/1) in the CPU DT node.
-
-
-Example:
-
-Example 1: Dual-cluster, Quad-core per cluster. CPUs within a cluster switch
-DCVS state together.
