From aaa58d0e932c518bdb1d9dc767876d7a8c68e17e Mon Sep 17 00:00:00 2001 From: Yangbo Lu Date: Wed, 16 Sep 2015 14:36:10 +0800 Subject: [PATCH] mmc: sdhci-pltfm: enable interrupt mode to detect card for ls1021a Enable interrupt mode to detect card instead of polling mode for ls1021a by removing the quirk SDHCI_QUIRK_BROKEN_CARD_DETECTION. This could improve data transferring performance and avoid the call trace caused by polling card status sometime.
