Your changelog said:

>   - Remove ma35d1-pinfunc.h which is unused after update definition of
'nuvoton,pins'.

You forgot to add:

" - Do not test the bindings before sending"

I assume none of the driver changes compile either.

allOf goes before additionalProperties.

This goes after patternProperties

Drop allOf, just $ref

Drop this and other "true", why do you need them here?
