+Qualcomm Technologies, Inc. SPMI PMIC clock divider (clkdiv)
+
+clkdiv configures the clock frequency of a set of outputs on the PMIC.
+These clocks are typically wired through alternate functions on
+gpio pins.
+
+=======================
+Properties
+=======================
+
+- compatible
+ Usage: required
+ Value type: <string>
+ Definition: must be "qcom,spmi-clkdiv".
+
+- reg
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: base address of CLKDIV peripherals.
+
+- qcom,num-clkdivs
+ Usage: required
+ Value type: <u32>
+ Definition: number of CLKDIV peripherals.
+
+- clocks:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: reference to the xo clock.
+
+- clock-names:
+ Usage: required
+ Value type: <stringlist>
+ Definition: must be "xo".
+
+- clock-cells:
+ Usage: required
+ Value type: <u32>
+ Definition: shall contain 1.
+
+=======
+Example
+=======
+
+pm8998_clk_divs: clock-controller@5b00 {
+ compatible = "qcom,spmi-clkdiv";
+ reg = <0x5b00>;
+ #clock-cells = <1>;
+ qcom,num-clkdivs = <3>;
+ clocks = <&xo_board>;
+ clock-names = "xo";
+
+ assigned-clocks = <&pm8998_clk_divs 1>,
+ <&pm8998_clk_divs 2>,
+ <&pm8998_clk_divs 3>;
+ assigned-clock-rates = <9600000>,
+ <9600000>,
+ <9600000>;
