> (P3H2440/P3H2441/P3H2840/P3H2841) family of multiport I3C hub devices.
> These devices connect to a host via I3C/I2C/SMBus and expose multiple

> All variants share the same register interface. The driver reads the target-port
> count from DEV_CAPAB and applies the DT configuration, so no per-compatible
