The change itself is justified, the "justification" in the message might need some rework, as this sounds more like a kernel-side issue, while the extcon should always be optional. Something like: The extcon property is used to detect the cable-state but some boards just connect the type-c phy to a regular USB-A connector without any power-delivery and thus no controller reporting the cable-state. So the extcon property is not really a required property, move it to be optional instead.
