Subject: [PATCH] tty/of_serial: add missing ns16550a id
Date: Tue, 24 Nov 2009 10:22:41 +0000 [thread overview]
Message-ID: <200911241022.41078.arnd@arndb.de> (raw)
From: Michal Simek <monstr@monstr.eu>
Many boards have a bug-free ns16550 compatible serial port, which we should
register as PORT_16550A. This introduces a new value "ns16550a" for the
compatible property of of_serial to let a firmware choose that model instead
of using the crippled PORT_16550 mode.
