| |
AM654 uses a UART controller that is only partially compatible with existing 8250 UART. UART DMA integration is substantially different and even a match against standard 8250 or omap4 would result in non-working UART once DMA is enabled by default.
Introduce a specific compatible to help build up the differences in follow on patches.
