+
+Required properties:
+- compatible: Should contain "nxp,pcf8523".
+- reg: I2C address for chip.
+
+Optional property:
+- quartz-load-femtofarads: The capacitive load of the quartz(x-tal),
+ expressed in femto Farad (fF). Valid values are 7000 and 12500.
+ Default value (if no value is specified) is 12500fF.
+
+Example:
+
+pcf8523: rtc@68 {
+ compatible = "nxp,pcf8523";
+ reg = <0x68>;
+ quartz-load-femtofarads = <7000>;
