 Optional properties:
 - nvidia,enable-modem-interrupt: Enable modem interrupts. Should be enable
 		only if all 8 lines of UART controller are pinmuxed.
+- nvidia,adjust-baud-rates: List of entries providing percentage of baud rate
+  adjustment within a range.
+  Each entry contains sets of 3 values. Range low/high and adjusted rate.
+  <range_low range_high adjusted_rate>
+  When baud rate set on controller falls within the range mentioned in this
+  field, baud rate will be adjusted by percentage mentioned here.
+  Ex: <9600 115200 200>
+  Increase baud rate by 2% when set baud rate falls within range 9600 to 115200

+Baud Rate tolerance:
+  Standard UART devices are expected to have tolerance for baud rate error by
+  -4 to +4 %. All Tegra devices till Tegra210 had this support. However,
+  Tegra186 chip has a known hardware issue. UART Rx baud rate tolerance level
+  is 0% to +4% in 1-stop config. Otherwise, the received data will have
+  corruption/invalid framing errors. Parker errata suggests adjusting baud
+  rate to be higher than the deviations observed in Tx.
+
+  Tx deviation of connected device can be captured over scope (or noted from
+  its spec) for valid range and Tegra baud rate has to be set above actual
+  Tx baud rate observed. To do this we use nvidia,adjust-baud-rates
+
+  As an example, consider there is deviation observed in Tx for baud rates as
+  listed below.
+  0 to 9600 has 1% deviation
+  9600 to 115200 2% deviation
+  This slight deviation is expcted and Tegra UART is expected to handle it. Due
+  to the issue stated above, baud rate on Tegra UART should be set equal to or
+  above deviation observed for avoiding frame errors.
+  Property should be set like this
+  nvidia,adjust-baud-rates = <0 9600 100>,
+  			     <9600 115200 200>;
