I'm trying to interface an external duart XR68M752IM48 to my custom ls1021a-twr board's ifc bus,
Can you please tell me what are the changes I may have to make to the driver to interface this chip and also the changes I have to make in the dts file fot configure a duart node?
See as example the AN12098:
It looks like the driver is needed the XR68M752IM48 using as duart on the LS1021a board.
The LS1021a supports 6 LPUARTs. Usually these UART are used if additional UARTs are needed.
Have a great day,
