From: Yangbo Lu Date: Mon, 1 Jun 2015 05:47:12 +0000 (+0800) Subject: mmc: sdhci-of-esdhc: enable interrupt mode to detect card X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=74fd5e30cc0b201a3800eb3743e059f34bd57fbf;p=openwrt%2Fstaging%2Fblogic.git mmc: sdhci-of-esdhc: enable interrupt mode to detect card Enable interrupt mode to detect card instead of polling mode for P1020/P4080/P5020/P5040/T1040 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.
