While renaming the file to .yaml I would like to also rename it to 1195.
It would need to be 1x9x to cover RTD1195 and e.g. RTD1296, and looking
forward the wildcard may need to be 1xxx to cover also RTD1619, which
quickly becomes unrecognizable.

Fixed.

This reveals a bug in the original binding example. Fixed to -rtc.

We can't. You acked the clk binding but the driver never got any review,
so it didn't get merged and cannot be depended on here.

I've changed it to an artificial 42 so that dt_binding_check passes.
I've also needed to fix the indentation to 4 spaces.
