-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>;
