From: Harsh Daniel <harshdaniel66356@gmail.com>
Add device tree bindings for the compatible strings used in the
staging/most/dim2 driver to resolve checkpatch warnings:
- fsl,imx6q-mlb150
- renesas,mlp and renesas,rcar-gen3-mlp
- xlnx,axi4-os62420_3pin-1.00.a and xlnx,axi4-os62420_6pin-1.00.a
These bindings document the MediaLB DIM2 module found in Freescale
i.MX6Q, Renesas R-Car, and Xilinx FPGA platforms.

My bot found errors running 'make dt_binding_check' on your patch:
yamllint warnings/errors:
dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/media/fsl,imx6q-mlb150.yaml: properties:clock-names: {'minItems': 1, 'maxItems': 2, 'items': [{'const': 'mlb'}, {'const': 'pll8_mlb'}]} 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
doc reference errors (make refcheckdocs):
See https://patchwork.kernel.org/project/devicetree/patch/20260130141442.139640-1-harshdaniel66356@gmail.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.

These all look pretty similar and it's the same h/w block, so they
should be 1 binding doc.

Drop block name 'mlb'. Use 'core' or something related to the function.
