From cdb3496595cd4bfa9836bf554edef5e43016b62e Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Fri, 17 Jun 2011 09:45:07 -0600 Subject: tty/serial: Fix XSCALE serial ports, e.g. ce4100 commit 5568181f188ae9485a0cdbea5ea48f63d186a298 upstream. Commit 4539c24fe4f92c09ee668ef959d3e8180df619b9 "tty/serial: Add explicit PORT_TEGRA type" introduced separate flags describing the need for IER bits UUE and RTOIE. Both bits are required for the XSCALE port type. While that patch updated uart_config[] as required, the auto-probing code wasn't updated to set the RTOIE flag when an XSCALE port type was detected. This caused such ports to stop working. This patch rectifies that.
