Subject[PATCH 3.14 19/23] ARC: [nsimosci] Change .dts to use generic 8250 UART
Date
3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mischa Jonker <mjonker@synopsys.com>

commit 6eda477b3c54b8236868c8784e5e042ff14244f0 upstream.

The Synopsys APB DW UART has a couple of special features that are not
in the System C model. In 3.8, the 8250_dw driver didn't really use these
features, but from 3.9 onwards, the 8250_dw driver has become incompatible
with our model.
