61 List of entries providing percentage of baud rate adjustment within a range. Each entry
62 contains a set of 3 values: range low/high and adjusted rate. When the baud rate set on the
63 controller falls within the range mentioned in this field, the baud rate will be adjusted by
68 Increase baud rate by 2% when set baud rate falls within range 9600 to 115200.
70 Standard UART devices are expected to have tolerance for baud rate error by -4 to +4 %. All
72 issue. UART RX baud rate tolerance level is 0% to +4% in 1-stop config. Otherwise, the
74 baud rate to be higher than the deviations observed in TX.
77 valid range and Tegra baud rate has to be set above actual TX baud rate observed. To do this
78 we use nvidia,adjust-baud-rates.
80 As an example, consider there is deviation observed in TX for baud rates as listed below. 0
82 Tegra UART is expected to handle it. Due to the issue stated above, baud rate on Tegra UART
