* NXP PCF85063 Real Time Clock
Required properties:
- compatible: Should one of contain:
"nxp,pcf85063",
"nxp,pcf85063a",
"nxp,pcf85063tp",
"microcrystal,rv8263"
- 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 7000fF.
Optional child node:
- clock: Provide this if the square wave pin is used as boot-enabled fixed clock.
Example:
pcf85063: rtc@51 {
compatible = "nxp,pcf85063";
reg = <0x51>;
quartz-load-femtofarads = <12500>;
clock {
compatible = "fixed-clock";
#clock-cells = <0>;
clock-frequency = <32768>;
};
};
