The lan969x switch chip (upstreaming efforts beginning soon) has ten 10G SERDES'es which share the same features and data rates as the Sparx5 10G SERDES'es. Lets take advantage of this and reuse the existing SERDES driver for lan969x. In order to do this, we add a new indirection layer to the register macros, that takes register differences into account. Additionally, we add driver match data for other differences that we need to handle. These other differences are handled by a combination of constants (eg. the number of SERDES'es), ops and if's Patch #1 adds support for match data. Patch #2 adds a struct to handle constants and adds a constant for the number of SERDES'es. Patch #3 adds a constant for the number of CMU's Patch #4 adds a struct for ops and adds a function for setting SERDES type. Patch #5 adds a function for getting the number of CMU's. Patch #6 adds register macro indirection layer. Patch #7 adds SERDES target types (eg. Sparx5, lan969x) to be used for branching out based on the target. Patch #8 adds support for lan969x in the Sparx5 dt-bindings. Patch #9 introduces the new lan969x SERDES driver.
