From: Konstantin Pugin <ria.freelander@xxxxxxxxx> EXAR XR20M1172 UART is mostly SC16IS762-compatible, but it has additional register which can change UART multiplier to 4x and 8x, similar to UPF_MAGIC_MULTIPLIER does. So, I used this flag to guard access to its specific DLD register. It seems than other EXAR SPI UART modules also have this register, but I tested only XR20M1172.
