2011-03-17mmc: core: export function mmc_do_release_host()Ulf Hansson2-1/+10
When using mmc_try_claim_host the corresponding release function is mmc_do_release_host, which then also must be exported.

2011-03-17mmc: sdio: remember new card RCA when redetecting cardStefan Nilsson XK1-0/+8
During redetection of a SDIO card, a request for a new card RCA was submitted to the card, but was then overwritten by the old RCA. This caused the card to be deselected instead of selected when using the incorrect RCA. This bug's been present since the "oldcard" handling was introduced in 2.6.32.

2011-03-16mmc: core: comment on why sdio_reset is done at init timePhilip Rakity1-0/+6
sdio_reset sends a CMD52 to reset the sdio card. This is highly recommended for sdio cards being reinitialized. Since we do not know if the card is being reinitialized we just send the command. SD/eMMC cards are supposed to ignore the CMD before the CMD0. Document why we are doing this. Signed-off-by: Philip Rakity <[email protected]> Signed-off-by: Chris Ball <[email protected]>

Enhanced area feature is a new feature defined in eMMC4.4 standard. This user data area provides higher performance/reliability, at the expense of using twice the effective media space due to the area using SLC. The MMC driver now reads out the enhanced area offset and size and adds them to the device attributes in sysfs. Enabling the enhanced area can only be done once, and should be done in manufacturing. To use this feature, bit ERASE_GRP_DEF should also be set. Documentation/ABI/testing/sysfs-devices-mmc describes the two new attributes.
