The bindings, just like the driver, are quite limited, e.g. do not support regulator supplies. Signed-off-by: Krzysztof Kozlowski Reviewed-by: Rob Herring --- Changes since v3: 1. Document also two lane setup. Changes since v2: 1. Remove clock-frequency, add reset GPIOs, add supplies. 2. Use additionalProperties. Changes since v1: 1.
