My bot found errors running 'make dt_binding_check' on your patch:
yamllint warnings/errors:
dtschema/dtc warnings/errors:
Error: Documentation/devicetree/bindings/i2c/i2c-imx-lpi2c.example.dts:31.37-38 syntax error
FATAL ERROR: Unable to parse input tree
make[1]: *** [scripts/Makefile.lib:377: Documentation/devicetree/bindings/i2c/i2c-imx-lpi2c.example.dt.yaml] Error 1

make: *** [Makefile:1414: dt_binding_check] Error 2
See https://patchwork.ozlabs.org/patch/1462762
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.
