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. Signed-off-by: Daniel Machon --- Changes in v2: - Changed the subject and commit description. - Added compatible strings for all lan969x SKU's in the dt-bindings. - Got rid of example in dt-bindings. - Added new compatible string: lan9691-serdes to driver. - Link to v1: https://lore.kernel.org/r/20240906-sparx5-lan969x-serdes-driver-v1-0-8d630614c58a@microchip.com --- Daniel Machon (9): phy: sparx5-serdes: add support for private match data phy: sparx5-serdes: add constants to match data phy: sparx5-serdes: add constant for the number of CMU's phy: sparx5-serdes: add ops to match data phy: sparx5-serdes: add function for getting the CMU index phy: sparx5-serdes: add indirection layer to register macros phy: sparx5-serdes: add support for branching on chip type dt-bindings: phy: sparx5: document lan969x phy: lan969x-serdes: add support for lan969x serdes driver .../bindings/phy/microchip,sparx5-serdes.yaml | 17 +- drivers/phy/microchip/sparx5_serdes.c | 195 +++++- drivers/phy/microchip/sparx5_serdes.h | 44 +- drivers/phy/microchip/sparx5_serdes_regs.h | 746 ++++++++++++++------- 4 files changed, 706 insertions(+), 296 deletions(-) --- base-commit: 221f9cce949ac8042f65b71ed1fde13b99073256 change-id: 20240822-sparx5-lan969x-serdes-driver-8389dbdd9a89 Best regards,
