We have couple of standard but rare used baudrates which are not supported by 1,8432MHz reference frequency. Besides that user can potentially ask for any baudrate (via BOTHER flag) and we currently don't fully support that. Since clk-fractional-divider is moved to use rational best approximation for reference frequency we may amend the driver to support whatever user wants.
