Subject: [PATCH] mmc: sdhci-pltfm: Added sdhci-adjust-timeout quirk
Date: Mon, 5 Dec 2011 16:55:20 +0800 [thread overview]
Message-ID: <1323075320-9138-1-git-send-email-X.Xie@freescale.com> (raw)
In-Reply-To: <y>
Some controller provides an incorrect timeout value for transfers,
So it need the quirk to adjust timeout value to 0xE.
E.g. eSDHC of MPC8536, P1010, and P2020.
