[v8,15/16] media: dt-bindings: Add TI J721E CSI2RX
Commit Message
From: Pratyush Yadav <p.yadav@ti.com>
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.

v7->v8:
- Drop "Device Tree Bindings" from title
- Rename "Wrapper" to "Shim" in title as that is the name referred in
the TRM and other places
- Update maintainer to myself
- Drop items from compatible as only a single element is present
- Rename compatible to "ti,j721e-csi2rx-shim" to distinguish from the
SoC-specific CSI2RX bridge compatible

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.

Sorry I missed this warning from v7.
This patch depends on 9536cc949235 ("media: dt-bindings: cadence-csi2rx:
Convert to DT schema") which is part of linux-next.
The base for this series should be linux-next/master
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
instead of 6.5-rc1.

+description: |
+ The TI J721E CSI2RX Shim 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.
