Why do I need these? I can go read your dts files if I need more
examples.

Hi,
These examples were present in the dt-binding before the convertion to
json :
https://patchwork.kernel.org/project/linux-arm-kernel/patch/20200122095558.22553-3-benjamin.gaignard@st.com/
Would you like a v2 with this precision ?
However this is not an essential patch, we can just drop it.
