Subject: [PATCH v2] dt-bindings: usb: add common Type-C USB Switch schema
Several bindings implement parts of Type-C USB orientation and mode
switching, and retiming. Keep definition of such properties in one
place, new usb-switch schema, to avoid duplicate defines.
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
---
Changes in v2:
1. Fix language typos handle->handler (Luca)
2. Drop debugging left-over (Luca)
