-Qualcomm MSM8916 A53 PLL Binding
---------------------------------
-The A53 PLL on MSM8916 platforms is the main CPU PLL used used for frequencies
-above 1GHz.
-
-Required properties :
-- compatible : Shall contain only one of the following:
-
-		"qcom,msm8916-a53pll"
-
-- reg : shall contain base register location and length
-
-- #clock-cells : must be set to <0>
-
-Example:
-
-	a53pll: clock@b016000 {
-		compatible = "qcom,msm8916-a53pll";
-		reg = <0xb016000 0x40>;
-		#clock-cells = <0>;
-	};
