From ccd8350d06c6df5dca868fefbd925af8ef55ac12 Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Tue, 19 Jun 2018 14:44:49 -0500 Subject: [PATCH] dt-bindings: serial: 8250_omap: Add compatible for AM654 UART controller 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.
