Binding
Documentation/devicetree/bindings/clock/silabs,si5341.txt
doesn't contain it
but driver drivers/clk/clk-si5341.c is reading it.

1345                 config[num].always_on =
1346                         of_property_read_bool(child, "always-on");

It is there from 2019 when driver has been added.

If it is not standard clock property it should be moved to standard one.
And DT binding should be converted to yaml with all properties used today.

Thanks,
Michal
