Re: [PATCH v7 1/2] dt-bindings: phy: qcom: Add CSI2 C-PHY/DPHY schema

[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The device tree example fails schema validation because `port@2`'s endpoint includes `data-lanes` and `clock-lanes` which are forbidden by the schema.

dt-bindings: phy: qcom: Add CSI2 C-PHY/DPHY schema

This commit adds a new base schema for the x1e80100 MIPI CSI2 PHY devices.
It supports CPHY, DPHY, and DPHY split-mode by modeling the CSIPHY devices
as individual nodes with three distinct ports.

[Severity: Low]
Will this example fail dt_binding_check schema validation?

The schema definition above for port@2's endpoint points to endpoint-base and
sets unevaluatedProperties to false, without locally defining data-lanes or
clock-lanes.

However, the example uses them here. Does the port@2 definition need a
reference to video-interfaces.yaml like the other ports, or should these
properties be removed from the example?
