[PATCH 3/3] sdhci-s3c: add support for new card detection methods

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

[PATCH 2/3] sdhci-s3c: add support for the non standard minimal clock value

S3C SDHCI host controller can change the source for generating mmc clock. By default host bus clock is used, what causes some problems on machines with 133MHz bus, because the SDHCI divider cannot be as high get proper clock value for identification mode. This is not a problem for the controller, b

BTRFS is broken with discard request?

Deal all, Now I got test the btrfs with discard option on MMC (implemented discard request). but I can't test the iozone benchmark test program with I/O error. Of course I disabled the discard option. it works well. and discard handling is tested with VFAT well. So I think BTRFS discard request s

From: Kishore Kadiyala This patch improves low speeds for SD cards. OMAP-MMC controller's can support maximum bus width of '8'. when bus width is mentioned as "8" in controller data,the SD stack will check whether bus width is "4" and if not it will set bus width to "1" and there by degrading per
