For DS1302, this is probable true.
Some devices may support both 4-wire or 3-wire mode?
IIRC yes.
Just for the record, the datasheet says it's exclusively 3-wire. But
it's not important...

Yeah, that one make sense. But if the DT is only overriding the maximum
device frequency that the driver should otherwise be setting, why is
spi-max-frequency a _required_ property?
That's a good question. Legacy?
It's a documentation error.
