2010-10-23mmc: sdhci: split up sdhci.h for sdhci-pltfm usersGiuseppe Cavallaro1-0/+144
Some platforms based on sdhci-pltfm need to set their own quirks. Previously to this patch, the quirks were in drivers/mmc/host/sdhci.h. This patch splits drivers/mmc/host/sdhci.h into two parts: * drivers/mmc/host/sdhci.h includes the HC registers and I/O accessors. * include/linux/mmc/sdhci.h includes the sdhci structure and quirks. Instead of including drivers/mmc/host/sdhci.h, -pltfm drivers should now include include/linux/mmc/sdhci.h and include/linux/sdhci-pltfm.h. This patch avoids adding/changing the calls/flags in the sdhci_pltfm_data structure. It has been tested on STM platforms (e.g. STx7106, STx7108, STx5206) where the driver is configured and used as shown in the example below: [snip] static int mmc_pad_resources(struct sdhci_host *sdhci) { if (!devm_stm_pad_claim(sdhci->mmc->parent, &stx7108_mmc_pad_config, dev_name(sdhci->mmc->parent))) return -ENODEV; return 0; } static struct sdhci_pltfm_data stx7108_mmc_platform_data = { .init = mmc_pad_resources, .quirks = SDHCI_QUIRK_NO_ENDATTR_IN_NOPDESC, }; static struct platform_device stx7108_mmc_device = { .name = "sdhci", [snip] Note: drivers/mmc/host/sdhci.h now also includes linux/mmc/sdhci.h, and no modifications should be needed on other sdhci-<XXX> drivers.

2010-10-23mmc: Fixes for Dual Data Rate (DDR) supportAdrian Hunter2-1/+7
The DDR support patch needs the following fixes: - The block driver does not need to know about DDR, any more than it needs to know about bus width. - Not only the card must be switched to DDR mode. The host controller must also be configured, which is done through the 'set_ios()' function. - Do not set the DDR mode state until after the switch command is successful. - Setting block length is not supported in DDR mode. Make that a core function and change the other place it is used (mmc_test) also. Signed-off-by: Adrian Hunter <[email protected]> Signed-off-by: Chris Ball <[email protected]>

2010-10-23mmc: Move regulator handling closer to coreLinus Walleij1-1/+21
After discovering a problem in regulator reference counting I took Mark Brown's advice to move the reference count into the MMC core by making the regulator status a member of struct mmc_host. I took this opportunity to also implement NULL versions of the regulator functions so as to rid the driver code from some ugly #ifdef CONFIG_REGULATOR clauses.

2010-10-23mmc: Make ID freq configurableHein Tibosch1-0/+1
In the latest releases of the mmc driver, the freq during initialization is set to a fixed 400 Khz. This was reportedly too fast for several users. As there doesn't seem to be an ideal frequency which-works-for-all, Pierre suggested to let the driver try several frequencies. This patch implements that idea. It will try mmc-initialization using several frequencies from an array 400, 300, 200 and 100. In case SDIO is broken, it'll still try to detect SDMEM, also at different freqs.

2010-10-23mmc: Add helper function to check if a card is removableMatt Fleming1-0/+8
There are two checks that need to be made when determining whether a card is removable. A host controller may set MMC_CAP_NONREMOVABLE if the controller does not support removing cards (e.g. eMMC), in which case the card is physically non-removable. Also the 'mmc_assume_removable' module parameter can be configured at module load time, in which case the card may be logically non-removable. A helper function keeps the logic in one place so that code always checks both conditions. Because this new function is likely to be called from modules we now need to export the mmc_assume_removable symbol.

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: add erase, secure erase, trim and secure trim operationsAdrian Hunter5-7/+64
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.

2010-08-11sdio: allow non-standard SDIO cardsGrazvydas Ignotas1-0/+2
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 Levitsky1-0/+3
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.

MX3 SoCs have a silicon bug which corrupts CRC calculation of multi-block transfers when connected SDIO peripheral doesn't drive the BUSY line as required by the specs. One way to prevent this is to only allow 1-bit transfers. Another way is playing tricks with the DMA engine, but this isn't mainline yet. So for now, we live with the performance drawback of 1-bit transfers until a nicer solution is found.

2010-03-24mmc: fix incorrect interpretation of card type bitsAdrian Hunter1-0/+1
In the extended CSD register the CARD_TYPE is an 8-bit value of which the upper 6 bits were reserved in JEDEC specifications prior to version 4.4. In version 4.4 two of the reserved bits were designated for identifying support for the newly added High-Speed Dual Data Rate. Unfortunately the mmc_read_ext_csd() function required that the reserved bits be zero instead of ignoring them as it should. This patch makes mmc_read_ext_csd() ignore the CARD_TYPE bits that are reserved or not yet supported. It also stops the function jumping to the end as though an error occurred, when it is only warns that the CARD_TYPE bits (that it does interpret) are invalid.

2010-03-06sdio: introduce API for special power management featuresNicolas Pitre3-0/+40
This patch series provides the core changes needed to allow SDIO cards to remain powered and active while the host system is suspended, and let them wake up the host system when needed. This is used to implement wake-on-lan with SDIO wireless cards at the moment. Patches to add that support to the libertas driver will be posted separately. This patch: Some SDIO cards have the ability to keep on running autonomously when the host system is suspended, and wake it up when needed. This however requires that the host controller preserve power to the card, and configure itself appropriately for wake-up. There is however 4 layers of abstractions involved: the host controller driver, the MMC core code, the SDIO card management code, and the actual SDIO function driver. To make things simple and manageable, host drivers must advertise their PM capabilities with a feature bitmask, then function drivers can query and set those features from their suspend method. Then each layer in the suspend call chain is expected to act upon those bits accordingly.

2009-09-23mmc: add ability to save power by powering off cardsAdrian Hunter1-0/+3
Power can be saved by powering off cards that are not in use. This is similar to suspend / resume except it is under the control of the driver, and does not require any power management support. It can only be used when the driver can monitor whether the card is removed, otherwise it is unsafe. This is possible because, unlike suspend, the driver still receives card detect and / or cover switch interrupts.

2009-04-22libertas: add support for Marvell SD8688 chipBing Zhao1-0/+2
libertas: add support for Marvell SD8688 chip Use RxPD->pkt_ptr to locate eth803 header in the packet received since SD8688/v10 firmware allows a gap between RxPD and eth803 header. Set SDIO block size to 256 for CMD53. The maximum block size for SD8688 WLAN function is set to 512 in TPLFE_MAX_BLK_SIZE. But using 512 as block size results upto 2K bytes data (4 blocks) being transferred and causes buffer overflow in firmware. Both changes above are backward compatible with earlier firmware versions for SD8385/SD8686.

2009-03-31MMC: regulator utilitiesDavid Brownell1-0/+5
Glue between MMC and regulator stacks ... verified with some OMAP3 boards using adjustable and configured-as-fixed regulators on several MMC controllers. These calls are intended to be used by MMC host adapters using at least one regulator per host. Examples include slots with regulators supporting multiple voltages and ones using multiple voltage rails (e.g. DAT4..DAT7 using a separate supply, or a split rail chip like certain SDIO WLAN or eMMC solutions).
