2008-07-15mmc,sdio: helper function for transfer paddingPierre Ossman
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>

2008-07-15au1xmmc: remove db1200 board code, rewrite probe.Manuel Lauss
Remove the DB1200 board-specific functions (card present, read-only, activity LED methods) and instead add platform data which is passed to the driver. This also allows for platforms to implement other carddetect schemes (e.g. dedicated irq) without having to pollute the driver code. The poll timer (used for pb1200) is kept for compatibility. With the board-specific stuff gone, the driver's ->probe() code can be cleaned up considerably.

2008-07-15at91_mci: Cover more AT91RM9200 and AT91SAM9261 errata.Ville Syrjala
According to the documentation the AT91SAM9261 MCI shares the block size limitations of the AT91RM9200 MCI. Also the errata documentation for AT91RM9200 and AT91SAM9261 state that stream commands are not supported. This has not been tested on actual hardware.

2008-07-15mmc: change .get_ro() callback semanticsAnton Vorontsov
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_spi: add support for card-detection pollingAnton Vorontsov
This patch adds new platform data variable "caps", so platforms could pass theirs capabilities into MMC core (for example, platforms without interrupt on the CD line will most probably want to pass MMC_CAP_NEEDS_POLL). New platform get_cd() callback provided to optimize polling. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-07-15mmc: add support for card-detection pollingAnton Vorontsov
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.

2008-07-15sdhci: move pci stuff to separate modulePierre Ossman
The SDHCI interface is not PCI specific, yet the Linux driver was intimitely connected to the PCI bus. This patch properly separates the PCI specific portion from the bus independent code.

2008-07-15sdhci: don't check block count for progressPierre Ossman
