1 * Maxim DS3231 Real Time Clock
4 - compatible: Should contain "maxim,ds3231".
5 - reg: I2C address for chip.
8 - #clock-cells: Should be 1.
10 overwrite the default clock names "ds3231_clk_sqw" and "ds3231_clk_32khz".
12 Each clock is assigned an identifier and client nodes can use this identifier
13 to specify the clock which they consume. Following indices are allowed:
14 - 0: square-wave output on the SQW pin
15 - 1: square-wave output on the 32kHz pin
17 - interrupts: rtc alarm/event interrupt. When this property is selected,
18 clock on the SQW pin cannot be used.
23 compatible = "maxim,ds3231";
