31 When baud rate set on controller falls within the range mentioned in this
32 field, baud rate will be adjusted by percentage mentioned here.
34 Increase baud rate by 2% when set baud rate falls within range 9600 to 115200
37 Standard UART devices are expected to have tolerance for baud rate error by
39 Tegra186 chip has a known hardware issue. UART Rx baud rate tolerance level
41 corruption/invalid framing errors. Parker errata suggests adjusting baud

46 Tx baud rate observed. To do this we use nvidia,adjust-baud-rates
