2010-08-11rtc/nuc900: modify enable/disable IRQs and driver data setting locationWan ZongShun1-11/+12
This patch does two modifications: (1) Adjust enable/disable IRQs location,enable it after rtc registration and disable it prior to unregistration. (2) Put 'platform_set_drvdata(pdev, nuc900_rtc)' in front of rtc registration still be safety, though there is no need to do this, when I move enable irq after rtc registration, I think still put 'platform_set_drvdata' before rtc registration that would be a good habit.

2010-08-11rtc/nuc900: fix checking of args during time-settingWan ZongShun1-4/+10
When a user application wants to set the rtc time, the RTC subsystem takes advantage of 'rtc_valid_tm(tm)' to check 'rtc_time *tm' value validity, it make sure the 'tm->tm_year' is larger than 70,so if '70< tm_year < 100', the '(settm->tm_year - 100)' will be negative. ' Setting the negative value to hardware register will be invalid, so I add the 'if' condition to make sure set a valid value to register.

2010-08-11sdhci-s3c: add support for new card detection methodsMarek Szyprowski2-0/+86
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 to some of the external interrupt lines or the presence of the card depends on some other actions (like enabling a power regulator). This patch adds support for all these cases. The following card detection methods are possible: 1. internal sdhci host card detect line 2. external event 3. external gpio interrupt 4. no card detect line, controller will poll for the card 5. no card detect line, card is permanently wired to the controller (once detected host won't poll it any more) By default, all existing code would use method #1, what is compatible with the previous version of the driver. In case of external event, two callbacks must be provided in platdata: ext_cd_init and ext_cd_cleanup. Both of them get a callback to a function that notifies the s3c-sdhci host contoller as their argument. That callback function should be called from the even dispatcher to let host notice the card insertion/removal. In case of external gpio interrupt, a gpio pin number must be provided in platdata (ext_cd_gpio parameter), as well as the information about the polarity of that gpio pin (ext_cd_gpio_invert). By default (ext_cd_gpio_invert == 0) gpio value 0 means 'card has been removed', but this can be changed to 'card has been removed' when ext_cd_gpio_invert == 1. This patch adds all required changes to sdhci-s3c driver.

2010-08-11sdhci-s3c: add support for the non standard minimal clock valueMarek Szyprowski2-2/+28
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, because it can generate lower frequencies from other clock sources. This patch changes sdhci driver to use get_min_clock() call if it has been provided.

2010-08-11sdio: allow non-standard SDIO cardsGrazvydas Ignotas2-6/+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.

2010-08-11mmc: fix all hangs related to mmc/sd card insert/removal during suspend/resumeMaxim Levitsky3-26/+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.

2010-08-11mmc: split mmc_sd_init_card()Michal Miroslaw3-119/+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.

The eMMC spec 4.4 and 4.3 + additional feature chips has CSD structure version 3 and version 3 have to check the CSD_STRUCTURE byte in the EXT_CSD register. Also fix EXT_CSD revision message.

2010-08-11vfs: use kmalloc() to allocate fdmem if possibleChangli Gao1-34/+23
Use kmalloc() to allocate fdmem if possible. vmalloc() is used as a fallback solution for fdmem allocation. A new helper function __free_fdtable() is introduced to reduce the lines of code. A potential bug, vfree() a memory allocated by kmalloc(), is fixed.
