Note that this doesn't say anything about (in)compatibility with generic R-Car Gen3 compatible devices (hint: yaml conversion?). New features: - Slave Clock Stretch Select, - Fast Mode+ Enable, - Enhanced First Bit Setup Cycle configuration. Looks like the R-Car V3U variant can be treated as a generic R-Car Gen3 variant (lacking the new features, of course). Gr{oetje,eeting}s, Geert

Applied to for-next, thanks!

FM+ doesn't need an update. It will just handle higher values for the bus frequency. This is also the most likely one to be supported in Linux. First Bit setup is not even supported yet in the basic version. Configuration via Linux is unclear same as SlaveClockStretch. Use cases are unclear, too, which we would need for implementating any of this.
