From: Pratyush Yadav <[email protected]>
TI's J721E uses the Cadence CSI2RX and DPHY peripherals to facilitate
capture over a CSI-2 bus. The TI CSI2RX platform driver glues all the
parts together.

+ The TI J721E CSI2RX Wrapper is a wrapper around Cadence CSI2RX bridge that
+ enables sending captured frames to memory over PSI-L DMA. In the J721E
+ Technical Reference Manual (SPRUIL1B) it is referred to as "SHIM" under the
+ CSI_RX_IF section.

doc reference errors (make refcheckdocs):
See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/[email protected]
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.

Your patch fails here. This error must be fixed or explain as dependency
in the patch changelog. Patch cannot be taken without that dependency.
