I'd like to have pmin-pascal, pmax-pascal as the last two honeywell specific
properties, since they are not to be used unless someone has custom silicon.
so we will still have a block moved just like above.
the most logic order is the one I proposed above:
honeywell,transfer-function:
[..]
honeywell,pressure-triplet:
[..]
honeywell,pmin-pascal:
[..]
honeywell,pmax-pascal:
[..]
since the last 3 are tied together as we will see below.
is there any reason you want this order to change?

when someone generates the dtbo files via
cpp -nostdinc -I include -I ${LINUX_SRC}/include/ -I arch -undef -x assembler-with-cpp ${file}.dts "${BUILD_DIR}/${file}.dts.preprocessed"
dtc -@ -I dts -O dtb -o "${BUILD_DIR}/${file}.dtbo" "${BUILD_DIR}/${file}.dts.preprocessed"
the schema is not checked in any way.
so unless people can be bothered to understand the yaml intricacies in the
bindings file, I feel they need to see that redundant information there, see below.

speaking for intricacies, if the allOf is removed, then a binding containing
honeywell,pmax-pascal = <840000>;
honeywell,pressure-triplet = "0015PA";
would be considered to be correct by the schema, but that would be the incorrect
result. so afaict allOf needs to stay, and so does the redundant text.
best regards,
peter
