Subject: [PATCH 0/4] Extend sdhci-esdhc-imx card_detect and write_protect support for mx5
Date: Fri, 10 Jun 2011 18:42:48 +0800 [thread overview]
Message-ID: <1307702572-22066-1-git-send-email-shawn.guo@linaro.org> (raw)
The card-present polling within sdhci based driver is very expensive
in terms of the impact to system performance. We observe a few
system performance issues from Freescale and Linaro on mx5 platforms,
which have been proved card polling related.
The patch set extends the current sdhci-esdhc-imx card_detect and
write_protect support to cover mx5 platforms, and solves above
performance issues.
Shawn Guo (4):
mmc: sdhci: fix interrupt storm from card detection
mmc: sdhci-esdhc-imx: SDHCI_CARD_PRESENT does not get cleared
mmc: sdhci-esdhc-imx: remove "WP" from flag ESDHC_FLAG_GPIO_FOR_CD_WP
mmc: sdhci-esdhc-imx: extend card_detect and write_protect support
