+Binding for Silicon Labs 570, 571, 598 and 599 programmable
+I2C clock generators.
+
+Reference
+This binding uses the common clock binding[1]. Details about the devices can be
+found in the data sheets[2][3].

+[2] Si570/571 Data Sheet
+    https://www.silabs.com/Support%20Documents/TechnicalDocs/si570.pdf
+[3] Si598/599 Data Sheet
+    https://www.silabs.com/Support%20Documents/TechnicalDocs/si598-99.pdf
+
+Required properties:
+ - compatible: Shall be one of "silabs,si570", "silabs,si571",
+			       "silabs,si598", "silabs,si599"
+ - reg: I2C device address.
+ - #clock-cells: From common clock bindings: Shall be 0.
+ - factory-fout: Factory set default frequency. This frequency is part specific.
+		 The correct frequency for the part used has to be provided in
+		 order to generate the correct output frequencies. For more
+		 details, please refer to the data sheet.
+ - temperature-stability: Temperature stability of the device in PPM. Should be
+			  one of: 7, 20, 50 or 100.
+
+Optional properties:
+ - clock-output-names: From common clock bindings. Recommended to be "si570".
+ - clock-frequency: Output frequency to generate. This defines the output
+		    frequency set during boot. It can be reprogrammed during
+		    runtime through the common clock framework.
+ - silabs,skip-recall: Do not perform NVM->RAM recall operation. It will rely
+		       on hardware loading of RAM from NVM at power on.
+
+Example:
+	si570: clock-generator@5d {
+		#clock-cells = <0>;
+		compatible = "silabs,si570";
+		temperature-stability = <50>;
+		reg = <0x5d>;
+		factory-fout = <156250000>;
+	};
