From 4245afff8b241426792d60b5b9078583f52d4029 Mon Sep 17 00:00:00 2001 From: Dong Aisheng Date: Wed, 27 May 2015 18:13:31 +0800 Subject: [PATCH] mmc: sdhci-esdhc-imx: add quirk SDHCI_QUIRK2_BROKEN_HS200 for imx6qdl The iMX6Q/DL can not support HS200 mode while iMX6SL and iMX6SX can, so introduce a new flag to distinguish them.
