P4080 ESDHC controller does not support 1.8V and 3.0V voltage. but the
host controller capabilities register wrongly set the bits.
This patch adds the workaround to correct the weird voltage setting bits.

Argh.
Actually, I think the inversion of the card status is a bug - certainly
for Versatile it is. It was on Realview as we

This patch enables SDHCI_QUIRK_NO_HISPD_BIT on Samsung SDHCI driver.
This solves detection problems with some external SD cards. This change
has been tested on S5PC100 and S5PC110. It has no inpact on driver
speed.

On some Samsung SoCs not all SDHCI controllers have card detect (CD)
line. For some embedded designs it is not even needed, because ususally
the device (like SDIO flash memory or wifi controller) is permanently
wired to the controller. There are also systems which have a card detect
line connected
Hello,
This is an updated version of the patches I've sent yesterday. I've

This patch series includes various updates to sdhci-s3c driver. The

S3C SDHCI host controller can change the source for generating mmc

The controller base address is referred from platform
resource instead of using #defines. This fixes the
compilation error when driver is compiled for msm7x30.

Hi,
I'm trying to improve throughput of the Marvell 8686 sdio wlan module.
Unfortunately I have to stick with kernel 2.6.22.
Everything works except for very bad datarate. So far the mxc_mmc
driver does not handle any SDIO interrupts. Could that be the reason
for the bad performance?
I figure
This patch adds the Arasan MMC/SD/SDIO driver
for the STM ST40 platforms. It is based on the
SDHCI driver.
It has been tested on the STx7106/STx7108/STx5289
platforms.
