Subject: [PATCH 0/3] serial: amba-pl011: fix race conditions during initialisation
Date: Tue, 10 Dec 2013 10:18:57 +0000 [thread overview]
Message-ID: <1386670740-16914-1-git-send-email-tixy@linaro.org> (raw)
When a UART that is being used for a kernel console is also opened
by user-side, e.g. for use as a terminal, then there are race conditions
which can lead to terminal input being disabled and console output being
corrupted. This small patch series fixes these.
