A Dnvidia,tegra20-hsuart.txt27 - nvidia,adjust-baud-rates: List of entries providing percentage of baud rate
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
45 its spec) for valid range and Tegra baud rate has to be set above actual
46 Tx baud rate observed. To do this we use nvidia,adjust-baud-rates
56 nvidia,adjust-baud-rates = <0 9600 100>,
