From a52cf086ace7e6107f399fcf37059dc9e02916f3 Mon Sep 17 00:00:00 2001 From: Lokesh Vutla Date: Sat, 22 Apr 2017 15:57:25 +0530 Subject: serial: omap: Support debug UART Add debug UART functions to permit omap specific ns16550 to provide an early debug UART. This is mostly in common with DEBUG_UART_NS16550 except for Mode definition register which is required for selecting UART mode(16x auto-baud or 13x mode).
