The Jetson Xavier NX board routes UARTA to the 40-pin header and UARTC to a 12-pin debug header. The UARTs can be used by either the Tegra Combined UART (TCU) driver or the Tegra 8250 driver. By default, the TCU will use UARTC on Jetson Xavier NX. Currently, device-tree for Xavier NX enables the TCU and the Tegra 8250 node for UARTC. Fix this by disabling the Tegra 8250 node for UARTC and enabling the Tegra 8250 node for UARTA.
