How can i support UART Tx with DMA(using UHCI driver api) and Rx without DMA(using UART driver api)?

Hi Support Team,

We are using ESP32 IDF version 2.1 and want to use UART DMA. here in this IDFversion 2.1 not provided support for UART DMA. So in earlier discussion with support team we got some sample code for UART DMA. here attached received uhci.tar.gz file from support team.

So the above mention driver file working fine for DMA init for UART Tx and Rx both. but I am facing issue while UART Tx with DMA(using UHCI driver api) and Rx without DMA(using UART driver api).

1. Is it possible to use UART Tx without dma and Rx with dma and vice versa?
2. If possible then do you have reference example or demo sample code to verify over ESP32? Could you please send those details with sample code if you have?

Let me know if need any details from our side regarding same.
