There is no upstream support for lan969x SoC yet. The upstreaming of the lan969x SoC has just begun, and this series is part of that upstreaming effort. The lan969x switch driver (not submitted yet) will depend on this SERDES driver, however, their functionality is really independent of each other. That is why I am also upstreaming the SERDES- and switch driver series independent of each other. If these series needs to somehow be connected, by link or whatever, then fine. If there is some preferred way to do this, then please let me know or point me in some direction.
