Subject: [PATCH 3/4] mci: imx-esdhc: add DSR support
Date: Tue, 14 Jan 2014 09:23:36 +0100 [thread overview]
Message-ID: <1389687817-30882-4-git-send-email-list-09_barebox@tqsc.de> (raw)
In-Reply-To: <1389687817-30882-1-git-send-email-list-09_barebox@tqsc.de>
From: Markus Niebel <Markus.Niebel@tqs.de>
having DSR support in mci-core we need a way to
forward the DSR value to the driver. Add it to
platform data for imx-esdhc
TODO: implement the same for other host controller
drivers
