However, devices with multiple nodes on the interconnect could have other constraints and may not match with the auto generated node ids. Hence, allow the driver to provide the preferred master and slave ids. Signed-off-by: Varadarajan Narayanan --- v8: Per review feedback, set master/slave ids explicitly.
