The LP5812 is a 4x3 RGB LED driver with an autonomous animation
engine and time-cross-multiplexing (TCM) support for up to 12 LEDs
or 4 RGB LEDs. It supports both analog (256 levels) and PWM (8-bit)
dimming, including exponential PWM for smooth brightness control.

My bot found errors running 'make dt_binding_check' on your patch:

yamllint warnings/errors:

dtschema/dtc warnings/errors:


doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250818012654.143058-2-trannamatk@gmail.com

I do not see any errors/warnings here.

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.

I followed the guideline and ran make dt_binding_check with the latest
dt-schema installed (pip3 install dtschema --upgrade). I don’t see any
errors or warnings for my ti,lp5812.yaml schema.

When I unset DT_SCHEMA_FILES and run the full check against all examples,
I do get errors/warnings - but they come from other existing schemas, not
from my patch, e.g.:

Documentation/devicetree/bindings/net/nfc/ti,trf7970a.yaml: properties:ti,rx-gain-reduction-db: '$ref' should not be valid under {'const': '$ref'}
Documentation/devicetree/bindings/regulator/infineon,ir38060.yaml: maintainers:0: 'Not Me.' does not match '@'
Documentation/devicetree/bindings/leds/issi,is31fl319x.yaml: properties:audio-gain-db: '$ref' should not be valid under {'const': '$ref'}
Documentation/devicetree/bindings/phy/fsl,imx8mq-usb-phy.yaml: properties:fsl,phy-pcs-tx-deemph-3p5db-attenuation-db: '$ref' should not be valid under {'const': '$ref'}

My schema (ti,lp5812.yaml) passes cleanly without any issues.
