* Maxim DS3231 Real Time Clock
Required properties:
see: Documentation/devicetree/bindings/i2c/trivial-admin-guide/devices.rst
Optional property:
- #clock-cells: Should be 1.
- clock-output-names:
overwrite the default clock names "ds3231_clk_sqw" and "ds3231_clk_32khz".
Each clock is assigned an identifier and client nodes can use this identifier
to specify the clock which they consume. Following indices are allowed:
- 0: square-wave output on the SQW pin
- 1: square-wave output on the 32kHz pin
- interrupts: rtc alarm/event interrupt. When this property is selected,
clock on the SQW pin cannot be used.
Example:
ds3231: ds3231@51 {
compatible = "maxim,ds3231";
reg = <0x68>;
#clock-cells = <1>;
};
device1 {
...
clocks = <&ds3231 0>;
...
};
device2 {
...
clocks = <&ds3231 1>;
...
};
