My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/iio/accel/bosch,bmi088.yaml: 'additionalProperties' is a required property
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/iio/accel/bosch,bmi088.yaml: ignoring, error in schema: 
warning: no schema found in file: ./Documentation/devicetree/bindings/iio/accel/bosch,bmi088.yaml

See https://patchwork.ozlabs.org/patch/1428668

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

Wow, fast response, thanks.

Updated my dtschema, fixed the match name as requested and v7 is ready 
to go. I'm awaiting feedback from the iio people so I can send a new 
patch set.

No problem. Happens to us all sometimes!

One thing inline below.

Thanks,

What if the board only has the INT2 pin connected?
That's looks to be a valid hardware configuration.

I'd suggest using interrupt-names to cover this.

Yeah makes sense. The pins have the same functionality, so either one will do.
