Subject: [PATCH v2 8/8] mmc: sdhci-esdhc-imx: add quirk SDHCI_QUIRK2_BROKEN_HS200 for imx6qdl
Date: Mon, 22 Sep 2014 17:12:11 +0800	[thread overview]
Message-ID: <1411377131-19741-9-git-send-email-b29396@freescale.com> (raw)
In-Reply-To: <1411377131-19741-1-git-send-email-b29396@freescale.com>

The iMX6Q/DL can not support HS200 mode while iMX6SL and iMX6SX can,
so introduce a new flag to distinguish them.
