2010-10-15mmc: sdio: fix SDIO suspend/resume regressionOhad Ben-Cohen1-0/+13
Fix SDIO suspend/resume regression introduced by 4c2ef25fe0b "mmc: fix all hangs related to mmc/sd card insert/removal during suspend/resume": PM: Syncing filesystems ... done. Freezing user space processes ... (elapsed 0.01 seconds) done. Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done. Suspending console(s) (use no_console_suspend to debug) pm_op(): platform_pm_suspend+0x0/0x5c returns -38 PM: Device pxa2xx-mci.0 failed to suspend: error -38 PM: Some devices failed to suspend 4c2ef25fe0b moved the card removal/insertion mechanism out of MMC's suspend/resume path and into pm notifiers (mmc_pm_notify), and that broke SDIO's expectation that mmc_suspend_host() will remove the card, and squash the error, in case -ENOSYS is returned from the bus suspend handler (mmc_sdio_suspend() in this case). mmc_sdio_suspend() is using this whenever at least one of the card's SDIO function drivers does not have suspend/resume handlers - in that case it is agreed to force removal of the entire card. This patch fixes this regression by trivially bringing back that part of mmc_suspend_host(), which was removed by 4c2ef25fe0b.

2010-09-09omap hsmmc: fix a racing case between kmmcd and omap_hsmmc_suspendEthan Du1-1/+1
If suspend called when kmmcd is doing host->ops->disable, as kmmcd already increased host->en_dis_recurs to 1, the mmc_host_enable in suspend function will return directly without increase the nesting_cnt, which will cause the followed register access carried out to the disabled host. mmc_suspend_host will enable host itself. No need to enable host before it. Also works on kmmcd will get flushed in mmc_suspend_host, enable host after it will be safe. So make the mmc_host_enable after it.

2010-09-09tmio_mmc: don't clear unhandled pending interruptsYusuke Goda1-4/+1
Previously, it was possible for ack_mmc_irqs() to clear pending interrupt bits in the CTL_STATUS register, even though the interrupt handler had not been called. This was because of a race that existed when doing a read-modify-write sequence on CTL_STATUS. After the read step in this sequence, if an interrupt occurred (causing one of the bits in CTL_STATUS to be set) the write step would inadvertently clear it. Observed with the TMIO_STAT_RXRDY bit together with CMD53 on AR6002 and BCM4318 SDIO cards in polled mode. This patch eliminates this race by only writing to CTL_STATUS and clearing the interrupts that were passed as an argument to ack_mmc_irqs()."

2010-09-09mmc: avoid getting CID on SDIO-only cardsDavid Vrabel1-3/+2
The introduction of support for SD combo cards breaks the initialization of all CSR SDIO chips. The GO_IDLE (CMD0) in mmc_sd_get_cid() causes CSR chips to be reset (this is non-standard behavior). When initializing an SDIO card check for a combo card by using the memory present bit in the R4 response to IO_SEND_OP_COND (CMD5). This avoids the call to mmc_sd_get_cid() on an SDIO-only card.

2010-08-12mmc_block: add discard supportAdrian Hunter2-3/+55
Enable MMC to service discard requests. In the case of SD and MMC cards that do not support trim, discards become erases. In the case of cards (MMC) that only allow erases in multiples of erase group size, round to the nearest completely discarded erase group.

2010-08-12mmc: add erase, secure erase, trim and secure trim operationsAdrian Hunter6-1/+525
SD/MMC cards tend to support an erase operation. In addition, eMMC v4.4 cards can support secure erase, trim and secure trim operations that are all variants of the basic erase command. SD/MMC device attributes "erase_size" and "preferred_erase_size" have been added. "erase_size" is the minimum size, in bytes, of an erase operation. For MMC, "erase_size" is the erase group size reported by the card. Note that "erase_size" does not apply to trim or secure trim operations where the minimum size is always one 512 byte sector. For SD, "erase_size" is 512 if the card is block-addressed, 0 otherwise. SD/MMC cards can erase an arbitrarily large area up to and including the whole card. When erasing a large area it may be desirable to do it in smaller chunks for three reasons: 1. A single erase command will make all other I/O on the card wait. This is not a problem if the whole card is being erased, but erasing one partition will make I/O for another partition on the same card wait for the duration of the erase - which could be a several minutes. 2. To be able to inform the user of erase progress. 3. The erase timeout becomes too large to be very useful. Because the erase timeout contains a margin which is multiplied by the size of the erase area, the value can end up being several minutes for large areas. "erase_size" is not the most efficient unit to erase (especially for SD where it is just one sector), hence "preferred_erase_size" provides a good chunk size for erasing large areas. For MMC, "preferred_erase_size" is the high-capacity erase size if a card specifies one, otherwise it is based on the capacity of the card. For SD, "preferred_erase_size" is the allocation unit size specified by the card. "preferred_erase_size" is in bytes.

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 Ignotas1-6/+30
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.
