[PATCH V7 0/6] Add device-tree support for Cypress CYPD4226

[Jon Hunter]

Add device-tree support for Cypress CYPD4226 Type-C controller and
enable for the Jetson AGX Orin board. This series is derived from the
series to enable USB host and device support for Jetson AGX Orin [0].
I have split this out from that series because it was getting quite
big.

[PATCH V7 2/6] i2c: nvidia-gpu: Add ACPI property to align with device-tree

[Jon Hunter]

From: Wayne Chang <waynec@nvidia.com>

Device-tree uses the 'firmware-name' string property to pass a name of
the firmware build to the Cypress CCGx driver. Add a new ACPI string
property to the NVIDIA GPU I2C driver to align with device-tree so that
we can migrate to using a common property name for both ACPI and
device-tree.

[PATCH V7 3/6] usb: typec: ucsi_ccg: Add OF support

[Jon Hunter]

From: Wayne Chang <waynec@nvidia.com>

Add device-tree support for the Cypress CCG UCSI driver. The device-tree
binding for the Cypress CCG device uses the standard device-tree
'firmware-name' string property to indicate the firmware build that is
used.

The NVIDIA GPU I2C driver has been updated to use an ACPI string
property that is also named 'firmware-build' and given that this was the
only users of the 'ccgx,firmware-build' property, we can now remove
support for this legacy property.

[PATCH V7 5/6] arm64: tegra: Populate USB Type-C Controller for Jetson AGX Orin

[Jon Hunter]

Add the USB Type-C controller that is present on the Jetson AGX Orin
board. The ports for the Type-C controller are not populated yet, but
will be added later once the USB host and device support for Jetson AGX
Orin is enabled.

This is based upon a patch from Wayne Chang <waynec@nvidia.com>.

Ah sorry yes I forgot this!

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/usb/cypress,cypd4226.yaml: More than one condition true in oneOf schema:
	{'description': 'Either unevaluatedProperties or additionalProperties '
	                'must be present',
	 'oneOf': [{'required': ['unevaluatedProperties']},
	           {'required': ['additionalProperties']}]}
	hint: Either unevaluatedProperties or additionalProperties must be present
	from schema $id: http://devicetree.org/meta-schemas/core.yaml#

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20230124114318.18345-2-jonathanh@nvidia.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.

Indeed. My schema was not up to date :-(

I see the error now and will fix this. Sorry for not catching.
