I remember in my previous review that I requested you to use git mv for
renaming this
If you do that you will endup diff stat something like this:
------------------------->cut<-----------------------------

b/Documentation/devicetree/bindings/pinctrl/qcom,sm8250-lpass-lpi-pinctrl.yaml
similarity index 97%
rename from

rename to
