[PATCH 0/3] add support for EXAR XR20M1172 UART

Posted by Konstantin 2 weeks, 1 day ago

From: Konstantin Pugin <ria.freelander@gmail.com>

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.
