Subject: [v2] mmc: sdhci-pltfm: enable interrupt mode to detect card for ls1021a
Date: Wed, 16 Sep 2015 14:36:10 +0800 [thread overview]
Message-ID: <1442385370-26961-1-git-send-email-yangbo.lu@freescale.com> (raw)
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.
