Subject: [PATCH 06/11] SERIAL: omap: allow hardware assisted IXANY mode to be disabled
Date: Tue, 16 Oct 2012 11:59:45 +0100 [thread overview]
Message-ID: <E1TO4sD-0000WI-4v@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20121016101458.GZ21164@n2100.arm.linux.org.uk>
Nothing was clearing the UART_MCR_XONANY bit, so once the ixany
mode gets set, there's no possibility to disable it. Clear this
bit when IXANY mode is cleared.
