Subject: [PATCH] drivers/mci: pxa writedata timeout
Date: Mon, 19 Dec 2011 10:17:18 +0100 [thread overview]
Message-ID: <1324286241-23083-2-git-send-email-robert.jarzmik@free.fr> (raw)
In-Reply-To: <1324286241-23083-1-git-send-email-robert.jarzmik@free.fr>
The write data timeout is too small for old cards,
especially the Transcend 256MBytes SD card. Increase it from
10ms to 100ms.
