Qualcomm Atheros DDR and APPS FABRICS scaling
------------------------------------------------

Required properties :
- compatible : "qcom,fab-scaling"
- clocks : defines each clock needed
- clock-names : contains clock names
- fab_freq_high : Turbo FABRIC frequency
- fab_freq_nominal : Nominal FABRIC frequency

Example:

fab-scaling {
	compatible = "qcom,fab-scaling";
	clocks = <&apps_fabric_clk>, <&ebi1_clk>;
	clock-names = "apps-fab-clk", "ddr-fab-clk";
	fab_freq_high = <533000000>;
	fab_freq_nominal = <400000000>;
};
