From: Hugo Villeneuve <hvilleneuve@xxxxxxxxxxxx> Hello, this patch series fixes enhanced/special register set accesses and Tx FIFO corruption. I have tested the changes on a custom board with two SC16IS752 DUART over a SPI interface using a Variscite IMX8MN NANO SOM. The four UARTs are configured in RS-485 mode. Thank you.
