Subject: [PATCH 7/7] mmc: sdhci-esdhc-imx: add quirk SDHCI_QUIRK2_BROKEN_HS200 for imx6qdl
Date: Wed, 3 Sep 2014 20:05:03 +0800 [thread overview]
Message-ID: <1409745903-26550-8-git-send-email-b29396@freescale.com> (raw)
In-Reply-To: <1409745903-26550-1-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.
