+Binding for TO CDCE925 programmable I2C clock synthesizers.
+
+Reference
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+[2] http://www.ti.com/product/cdce925
+
+The driver provides clock sources for each output Y1 through Y5.
+
+Required properties:
+ - compatible: Shall be "ti,cdce925"
+ - reg: I2C device address.
+ - clocks: Points to a fixed parent clock that provides the input frequency.
+ - #clock-cells: From common clock bindings: Shall be 1.
+
+Optional properties:
+ - xtal-load-pf: Crystal load-capacitor value to fine-tune performance on a
+ board, or to compensate for external influences.
+
+For both PLL1 and PLL2 an optional child node can be used to specify spread
+spectrum clocking parameters for a board.
+ - spread-spectrum: SSC mode as defined in the data sheet.
+ - spread-spectrum-center: Use "centered" mode instead of "max" mode. When
+ present, the clock runs at the requested frequency on average. Otherwise
+ the requested frequency is the maximum value of the SCC range.
+
+
+Example:
+
+ clockgen: cdce925pw@64 {
+ compatible = "cdce925";
+ reg = <0x64>;
+ clocks = <&xtal_27Mhz>;
+ #clock-cells = <1>;
+ xtal-load-pf = <5>;
+ /* PLL options to get SSC 1% centered */
+ PLL2 {
+ spread-spectrum = <4>;
+ spread-spectrum-center;
+ };
+ };
