2009-09-23mmc: make SDIO device/driver struct accessors publicNicolas Pitre1-0/+3
Especially with the PM framework, those are quite handy to have in driver code too. Signed-off-by: Nicolas Pitre <nico@marvell.com> Cc: <linux-mmc@vger.kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2009-09-23sdio: add MMC_QUIRK_LENIENT_FN0Ohad Ben-Cohen1-0/+7
Normally writes to SDIO function 0 outside the vendor specific CCCR registers are prohibited. To support embedded devices that require writes to SDIO function 0 outside this range (e.g. TI WL127x embedded sdio wifi device), MMC_QUIRK_LENIENT_FN0 is introduced. A card quirks field is added to `struct mmc_card' to support non-standard devices (e.g. embedded sdio devices).

2009-09-23sdio: add CD disable supportOhad Ben-Cohen1-1/+2
Add support to disconnect the pull-up resistor on CD/DAT[3] (pin 1) of the card. This may be desired on certain setups of boards, controllers and embedded sdio devices which do not need the card's pull-up. As a result, card detection is disabled and power is saved.

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.

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.

2008-07-27mmc: Add per-card debugfs supportHaavard Skinnemoen1-0/+2
For each card successfully added to the bus, create a subdirectory under the host's debugfs root with information about the card. At the moment, only a single file is added to the card directory for all cards: "state". It reflects the "state" field in struct mmc_card, indicating whether the card is present, readonly, etc. For MMC and SD cards (not SDIO), another file is added: "status". Reading this file will ask the card about its current status and return it. This can be useful if the card just refuses to respond to any commands, which might indicate that the card state is not what the MMC core thinks it is (due to a missing stop command, for example.)

When CONFIG_DEBUG_FS is set, create a few files under /sys/kernel/debug containing information about an mmc host's internal state. Currently, just a single file is created, "ios", which contains information about the current operating parameters for the bus (clock speed, bus width, etc.) Host drivers can add additional files and directories under the host's root directory by passing the debugfs_root field in struct mmc_host as the 'parent' parameter to debugfs_create_*.

2008-07-15mmc: remove multiwrite capabilityPierre Ossman1-6/+5
Relax requirements on host controllers and only require that they do not report a transfer count than is larger than the actual one (i.e. a lower value is okay). This is how many other parts of the kernel behaves so upper layers should already be prepared to handle that scenario. This gives us a performance boost on MMC cards.

2008-07-15mmc,sdio: helper function for transfer paddingPierre Ossman2-1/+4
There are a lot of crappy controllers out there that cannot handle all the request sizes that the MMC/SD/SDIO specifications require. In case the card driver can pad the data to overcome the problems, this commit adds a helper that calculates how much that padding should be. A corresponding helper is also added for SDIO, but it can also deal with all the complexities of splitting up a large transfer efficiently. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-07-15mmc: change .get_ro() callback semanticsAnton Vorontsov1-0/+12
Now get_ro() callback must return 0/1 values for its logical states, and negative errno values in case of error. If particular host instance doesn't support RO/WP switch, it should return -ENOSYS. This patch changes some hosts in two ways: 1. Now functions should be smart to not return negative values in "RO asserted" case (particularly gpio_ calls could return negative values for the outermost GPIOs). Also, board code usually passes get_ro() callbacks that directly return gpioreg & bit result, so at91_mci, imxmmc, pxamci and mmc_spi's get_ro() handlers need take special care when returning platform's values to the mmc core. 2. In case of host instance didn't implement get_ro() callback, it should really return -ENOSYS and let the mmc core decide what to do about it (mmc core thinks the same way as the hosts, so it isn't functional change).

2008-07-15mmc: add support for card-detection pollingAnton Vorontsov1-0/+11
Some hosts (and boards that use mmc_spi) do not use interrupts on the CD line, so they can't trigger mmc_detect_change. We want to poll the card and see if there was a change. 1 second poll interval seems resonable. This patch also implements .get_cd() host operation, that could be used by the hosts that are able to report card-detect status without need to talk MMC.

The default block size is the largest that's supported by both the card and the host, with a maximum of 512 to ensure aribitrarily sized transfer use the optimal (least) number of commands.
