What is each GPIO entry?
- i2c-adapter:
We already have i2c-bus and i2c-parent properties. Neither of those work for you?

- uart:
Nice and consistent. In 3 properties, we have 'adapter', 'controller' and <null>...
Also, DT generally uses 'serial' rather than 'uart'.

How would someone handle any of the properties defined in spi-peripheral-props.yaml?
