While at it, please also send a separate patch to add pinctrl yaml
file entries in MAINTAINERS, which currently contains:

F: Documentation/devicetree/bindings/pinctrl/qcom,*.txt

without which $ ./scripts/get_maintainer.pl would not indicate correct
results for your yaml dt-binding addition.

Thanks,
