You could refer to phy/mediatek/phy-mtk-mipi-csi-0-5.c".

During probe, the driver will parse each port, obtain the corresponding PHY (e.g., devm_phy_get(dev, "csi0"), devm_phy_get(dev, "csi1"), etc.), and operate the PHY for each port individually during stream on/off or power on/off.

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250707013154.4055874-3-shangyao.lin@mediatek.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

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 after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
