[PATCH v7 1/2] dt-bindings: iio: accel: Add bmi088 accelerometer bindings

[PATCH v7 1/2] dt-bindings: iio: accel: Add bmi088 accelerometer bindings

[Mike Looijmans]

This adds the device-tree bindings for the Bosch Sensortec BMI088 IMU,
the accelerometer part.

Signed-off-by: Mike Looijmans <mike.looijmans@topic.nl>

---

Changes in v7:
Add additionalProperties
Change bmi088_accel to bmi088-accel
Add interrupt-names and adjust description

Changes in v6:
I't been almost a year since the last commit, sorry...
Fixed the yaml errors
Add interrupt, vdd and vddio properties

Changes in v5:
submit together with driver code as patch series

Changes in v2:
convert to yaml format

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.example.dt.yaml: bmi088-accel@1: 'spi-max-frequency' does not match any of the regexes: 'pinctrl-[0-9]+'
	From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/iio/accel/bosch,bmi088.yaml

See https://patchwork.ozlabs.org/patch/1429940

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.

Just the issue the build bot found.  Otherwise looks good to me.

As per Rob's build bot you need.

spi-max-frequency: true

If that's all that comes up and Rob is happy with this I can fix that up whilst
applying.  Please try to run the checks suggested in Rob's build bot message
before submitting binding patches though.

There'll be a v8 it seems, so I've already added it. Seems that I need 
to upgrade those definition files every day...
