Subject: [PATCH 11/27] Blackfin Serial Driver: Fix bug - ircp fails on sir over Blackfin UART
Date: Fri, 10 Oct 2008 11:49:15 +0100 [thread overview]
Message-ID: <20081010104911.31597.88428.stgit@localhost.localdomain> (raw)
In-Reply-To: <20081010103447.31597.42992.stgit@localhost.localdomain>
From: Graf Yang <graf.yang@analog.com>
We now use the sir_dev/irtty_sir/uart/bfin_serial drivers framework
to monitor the TX status.
