| * at91_mci: Cover more AT91RM9200 and AT91SAM9261 errata.Ville Syrjala2008-07-15
| | | | | | | | | | | | | | | | | | | | | | 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.

| * at91_mci: AT91SAM9260/9263 12 byte write erratum (v2)Ville Syrjala2008-07-15
| | | | | | | | | | | | | | | | | | | | AT91SAM926[0/3] PDC must write at least 12 bytes. The code compiles and runs but the actual condition for this erratum did not trigger in my tests so it's unclear if it actually works as intended.

| | | | | | | | | | | | | | | | | | | | | | The at91 mci controller internal state machine seems to often crash. This can be fixed by resetting the controller after each command for at91rm9200 and by setting the MCI_BLKR register on at91sam926*.

| * mmc: change .get_ro() callback semanticsAnton Vorontsov2008-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| * mmc_spi: add support for card-detection pollingAnton Vorontsov2008-07-15
| | | | | | | | | | | | | | | | | | | | | | | | 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>
| * mmc: add support for card-detection pollingAnton Vorontsov2008-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the code path executing an HDIO_DRIVE_RESET ioctl is broken in various ways. Most importantly, it is treated as an out of band request in an illegal way which may very likely lead to system lock ups.
