Hi,
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,
Pavel Chubakov
Hi Pavel,
Is there any driver already available for this? also can you please explain in detail how to configure the kernel to add support for XR68M752IM48 .
