Message-ID: <20070523172739.1d3a918c@the-village.bc.nu>
Date: Wed, 23 May 2007 17:27:39 +0100
From: Alan Cox <alan@...rguk.ukuu.org.uk>
To: rmk@....linux.org.uk, akpm@...l.org, linux-kernel@...r.kernel.org
Subject: [PATCH] ARM/ARM26: Enable arbitary speed tty ioctls and split
input/output speed
Add the ioctls and values needed for this to the ARM26/ARM32 ports. The
actual code has been in the base kernel for a while and automatically
turns on when a port sets the required defines.
