commit: 5568181f188ae9485a0cdbea5ea48f63d186a298 From: Stephen Warren <[email protected]> Date: Fri, 17 Jun 2011 09:45:07 -0600 Subject: [PATCH] tty/serial: Fix XSCALE serial ports, e.g. ce4100
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.
