Hi,
This patch add support for MOXA Smartio MUE boards to 8250 driver.
I already submitted an independant driver based on the vendor one :
https://lkml.org/lkml/2016/2/1/720
But as Andy pointed out, it seems to be a better idea to add this support
directly in 8250 driver.
I was able to test this patch on a CP-168EL-A on PC.
