Can you please convert this to DT schema.
Of course, missed this point, sorry, reworked. Is there a HowTo
for writting a schema?

Normal naming is to use compatible string. So ti,cc1101.yaml for schema.

Is there a GDO1? Would be hard to add later because you can't change the
indices once defined.
Good point. There is a GDO1, so yes, this makes sense, added.

Ok.
+ - freq : used spi frequency for communication with cc1101 chip
What's this? Doesn't spi-max-frequency cover it?
Of course, removed.
Thanks for your time and review.
