* sdhci-s3c: add SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK quirkHyuk Lee2010-08-111-7/+3
| | | | | | | | | | | | | | On Samsung's SDMMC hosts the timeout clock is derivied from the SD Clock which is set dynamically. So checked SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK quirk and removed 'sdhci_s3c_get_timeout_clk' callback which doesn't need any more.

* sdio: allow non-standard SDIO cardsGrazvydas Ignotas2010-08-112-6/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are some chips (like TI WL12xx series) that can be interfaced over SDIO but don't support the SDIO specification, meaning that they are missing CIA (Common I/O Area) with all it's registers. Current Linux SDIO implementation relies on those registers to identify and configure the card, so non-standard cards can not function and cause lots of warnings from the core when it reads invalid data from non-existent registers. After this patch, init_card() host callback can now set new quirk MMC_QUIRK_NONSTD_SDIO, which means that SDIO core should not try to access any standard SDIO registers and rely on init_card() to fill all SDIO structures instead. As those cards are usually embedded chips, all the required information can be obtained from machine board files by the host driver when it's called through init_card() callback.

| | | | | | | | | | | | | | | | | | | Due to build system limitations, intermediate and final objects can't have the same names. And as we're going to start building SoC-specific objects, let's rename the module to sdhci-platform, into which we'll link sdhci-pltfm and SoC-specifc objects. There should be no issue in renaming as the driver uses modalias mechanism. This is exactly the same approach as in sdhci-of driver.

* mmc: omap: fix for bus width which improves SD card's peformance.Kishore Kadiyala2010-08-111-2/+15
| | | | | | | | | | | | | | | | | | | | | | 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 performance. This patch fixes the issue and improves the performance of SD cards.

* mmc: fix all hangs related to mmc/sd card insert/removal during suspend/resumeMaxim Levitsky2010-08-113-26/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | If you don't use CONFIG_MMC_UNSAFE_RESUME, as soon as you attempt to suspend, the card will be removed, therefore this patch doesn't change the behavior of this option. However the removal will be done by pm notifier, which runs while userspace is still not frozen and thus can freely use del_gendisk, without the risk of deadlock which would happen otherwise. Card detect workqueue is now disabled while userspace is frozen, Therefore if you do use CONFIG_MMC_UNSAFE_RESUME, and remove the card during suspend, the removal will be detected as soon as userspace is unfrozen, again at the moment it is safe to call del_gendisk. Tested with and without CONFIG_MMC_UNSAFE_RESUME with suspend and hibernate.

* mmc: split mmc_sd_init_card()Michal Miroslaw2010-08-113-119/+186
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This series adds support for SD combo cards to MMC/SD driver stack. SD combo consists of SD memory and SDIO parts in one package. Since the parts have a separate SD command sets, after initialization, they can be treated as independent cards on one bus. Changes are divided into two patches. First is just moving initialization code around so that SD memory part init can be called from SDIO init. Second patch is a proper change enabling SD memory along SDIO. I tried to move as much no-op changes to the first patch so that it's easier to follow the required changes to initialization flow for SDIO cards. This is based on Simplified SDIO spec v.2.00. The init sequence is slightly modified to follow current SD memory init implementation. Command sequences, assuming SD memory and SDIO indeed ignore unknown commands, are the same as before for both parts. This patch: Prepare for SD-combo (IO+mem) support by splitting SD memory card init and related functions.
