Can you direct reuse > p3h2x*'s driver. Both P3H2x4x and RTS490x are based on the I3C Hub Common Architecture Specification, so identical specification-defined registers are expected. However, the current P3H2x4x driver is device-specific rather than a generic implementation of the specification. Do you mean refactoring it into a common implementation for devices based on this specification, while keeping the device-specific parts separate?
