From 6eda477b3c54b8236868c8784e5e042ff14244f0 Mon Sep 17 00:00:00 2001 From: Mischa Jonker Date: Thu, 16 May 2013 19:36:08 +0200 Subject: ARC: [nsimosci] Change .dts to use generic 8250 UART 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.
