Can you please reorder like:
&i2c1 {
status = "okay";
clock-frequency = <400000>;
i2c-scl-internal-delay-ns = <12500>;
pinctrl-names = "default";
pinctrl-0 = <&i2c1_pins>;

Also, address and size cells are common properties and will not change
on a per-board basis: please define them in mt8186.dtsi instead.
Same for the other nodes.

Please perform a dtbs_check before pushing devicetrees upstream:
this node will give you a warning, bindings related warnings are
considered like code warnings and they shall not happen.
pinctrl-mt8186.yaml defines patternProperties as '-pins$'
so this should be:

Please fix.
