| Subject: ARC: [nsimosci] Change .dts to use generic 8250 UART |
| |
| 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. |
