Provide detailed changelog next time. And respond to EACH comment acknowledging that you understood it.

Please use standard email subjects, so with the PATCH keyword in the title. 'git format-patch -vX' helps here to create proper versioned patches. Another useful tool is b4. Skipping the PATCH keyword makes filtering of emails more difficult thus making the review process less convenient. A nit, subject: drop second/last, redundant "bindings". The "dt-bindings" prefix is already stating that these are bindings. See also: https://elixir.bootlin.com/linux/v6.7-rc8/source/Documentation/devicetree/b… > +properties: > + compatible: > + const: mediatek,mt8188-cam-yuv > + > + reg: > + minItems: 1 What, why?

You did not follow any existing patterns and this binding does not look at all as anything else. Why making this things up? Just use recently reviewed binding as starting point.

Review your patches before you post them. You should reach internally to mediatek colleagues to explain you how this process works.

Add camera isp7x module device document > > --- > > Changes in v2: > - Rename binding file to mediatek,mt8188-seninf-core.yaml > - Various fixes per review comments > - Update maintainers list > > Question for reviewer (CK): > > Hi CK, > > Thank you for your review and suggestions on this patch, especially for providing the reference patch (https://patchwork.kernel.org/project/linux-mediatek/list/?series=874617) and for mentioning in another patch ([V1,02/10] MEDIA: PLATFORM: MEDIATEK: ADD SENINF CONTROLLER) the suggestion to "Move the phy part to phy/mediatek/ folder. You could refer to phy/mediatek/phy-mtk-mipi-csi-0-5.c". > > After reading your comments and the reference patches, my understanding is that only the seninf-core driver should manage all ports internally, and each port corresponds to a PHY. 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. > > Could you please confirm if my understanding is correct? > If you have any additional reference patches or examples, I would greatly appreciate it. > > Thank you for your guidance! > > Best regards, > Shangyao > > Signed-off-by: shangyao.lin <shangyao.lin(a)mediatek.com> > --- > .../mediatek/mediatek,mt8188-seninf-core.yaml | 121 ++++++++++++++++++ > 1 file changed, 121 insertions(+) > create mode 100755 Documentation/devicetree/bindings/media/mediatek/mediatek,mt8188-seninf-core.yaml > My bot found errors running 'make dt_binding_check' on your patch: yamllint warnings/errors: ./Documentation/devicetree/bindings/media/mediatek/mediatek,mt8188-seninf-core.yaml:6:10: [error] string value is redundantly quoted with any quotes (quoted-strings) ./Documentation/devicetree/bindings/media/mediatek/mediatek,mt8188-seninf-core.yaml:121:4: [error] no new line character at the end of file (new-line-at-end-of-file) dtschema/dtc warnings/errors: /builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/media/mediatek/mediatek,mt8188-seninf-core.yaml: properties:clock-names: {'items': [{'const': 'clk_cam_seninf'}, {'const': 'clk_top_seninf'}, {'const': 'clk_top_seninf1'}, {'const': 'clk_top_camtm'}], 'minItems': 4, 'maxItems': 4} should not be valid under {'required': ['maxItems']} hint: "maxItems" is not needed with an "items" list from schema $id: http://devicetree.org/meta-schemas/items.yaml# /builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/media/mediatek/mediatek,mt8188-seninf-core.yaml: properties:clock-names: 'oneOf' conditional failed, one must be fixed: [{'const': 'clk_cam_seninf'}, {'const': 'clk_top_seninf'}, {'const': 'clk_top_seninf1'}, {'const': 'clk_top_camtm'}] is too long [{'const': 'clk_cam_seninf'}, {'const': 'clk_top_seninf'}, {'const': 'clk_top_seninf1'}, {'const': 'clk_top_camtm'}] is too short False schema does not allow 4 1 was expected 4 is greater than the maximum of 2 4 is greater than the maximum of 3 hint: "minItems" is only needed if less than the "items" list length from schema $id: http://devicetree.org/meta-schemas/items.yaml# /builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/media/mediatek/mediatek,mt8188-seninf-core.yaml: properties:reg-names: {'items': [{'const': 'base'}], 'minItems': 1, 'maxItems': 1} should not be valid under {'required': ['maxItems']} hint: "maxItems" is not needed with an "items" list from schema $id: http://devicetree.org/meta-schemas/items.yaml# /builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/media/mediatek/mediatek,mt8188-seninf-core.yaml: properties:reg-names: 'oneOf' conditional failed, one must be fixed: [{'const': 'base'}] is too short False schema does not allow 1 hint: "minItems" is only needed if less than the "items" list length from schema $id: http://devicetree.org/meta-schemas/items.yaml# /builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/media/mediatek/mediatek,mt8188-seninf-core.yaml: properties:reg: 'anyOf' conditional failed, one must be fixed: 'minItems' is not one of ['maxItems', 'description', 'deprecated'] hint: Only "maxItems" is required for a single entry if there are no constraints defined for the values.

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.
