Hi, You can find v4 of the series from: https://lore.kernel.org/all/20221101132032.1542416-1-tomi.valkeinen@xxxxxxxxxxxxxxxx/ You can find a longer introduction of the series in that version's cover letter. There has been a lot of changes to the DT bindings and the i2c-atr code in this version, but they are all fixes and cleanups, no architectural changes. The FPDLink drivers have not been changed, except to reflect the changes in the DT. I will send a diff between v4 and v5 to give a better idea of the changes. One thing that was discussed a bit but not handled in this version is the i2c-pool/i2c-alias topic. I believe we have three options: 1) use fixed addresses, defined in DT, 2) get the addresses from an i2c-pool, 3) dynamically reserve the addresses at runtime. The current series uses 2).
