Details

clock-src

int

The input clock select for IRTC.
0 <- 16.384 kHz
1 <- 32.768 kHz

This property is required.

Legal values: 0, 1

output-clk-en

int

Enable clock as an output for other peripherals to use.
0 <- No clock output
1 <- Fine 1Hz
2 <- Buffered Oscillator Clock
3 <- Coarse 1Hz
Default value ensures the output clock is turned off.
This is the reset value.

Legal values: 0, 1, 2, 3

clock-frequency

int

Clock frequency information for RTC operation

prescaler

int

RTC frequency equals clock-frequency divided by the prescaler value

alarms-count

int

Number of alarms supported by RTC device. The number of
alarms defaults to 0, which indicates that the RTC has
no alarms.
