Subject: [PATCH v1 3/4] serial: add an of-platdata driver for "snps,dw-apb-uart"
Add a driver for the "snps,dw-apb-uart" used in socfpga and others.
This driver is required to get OF_PLATDATA to work for socfpga.
It uses the ns16550 driver, converting the platdata from of-platdata
go the ns16550 format.

Might be a bit naïve question but why depend on SPL_OF_PLATDATA only?
What about CONFIG_OF_EMBED?
I'd happily switch my ARC boards on this driver and get rid of all
CONFIG_SYS_NS16550_xxx nonsense in include/configs/myboardname.h
I checked include/configs/socfpga_common.h again and by its using
Kconfig and DM_SERIAL, there are no CONFIG_SYS_NS16550_xxx defines left
(other than CONFIG_SYS_NS16550_SERIAL, which I will remove).
So it seems it's not a matter of a new driver but a matter of cleaning
up the boards to use DM_SERIAL, I guess?
Regards,
Simon
