Hi, Here's v5 of the outstanding fixes for Oxford Semiconductor 950 UARTs including most updates requested by Andy (thanks for your review!). Also while looking into an unrelated issue I have come across the DIV_ROUND_CLOSEST macro and updated 5/5 replacing equivalent handcoded calculations. I have verified that there is no change in machine code produced after this update with the i386 and RISC-V targets. Please apply. Maciej
