[PATCH v2 03/13] dt-bindings: usb: Add binding for Cypress cypd4226 I2C driver
Posted by Wayne Chang 2 years, 6 months ago 
add device-tree binding documentation for Cypress cypd4226 type-C
controller's I2C interface. It is a standard I2C slave with GPIO
input as IRQ interface.

Signed-off-by: Wayne Chang <waynec@nvidia.com>

V1 -> V2:Based on the review comments. Fix some addressed issues on
description, interrupts, cypress,firmware-build, connector, and 
additionalProperties properties. And also remove the status in the example.

I see warnings with this change ...

Documentation/devicetree/bindings/usb/cypress,cypd4226.yaml: 
'additionalProperties' is a required property
	hint: A schema without a "$ref" to another schema must define all 
properties and use "additionalProperties"
	from schema $id: http://devicetree.org/meta-schemas/base.yaml#


Looking at Rob's comments I believe we need ...

Thanks for the review.
Somehow I do not get the warnings in local test.
I'll apply the change into the next patch series.
