Some of the patches have been suggested by Andy Shevchenko following this dicussion: Link: https://lore.kernel.org/all/CAHp75VebCZckUrNraYQj9k=Mrn2kbYs1Lx26f5-8rKJ3RXeh-w@mail.gmail.com/ 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. I did not test the change on a SC16is7xx using I2C interface, as my custom board is only using SPI. Thank you.
