mmc: fix a race between card-detect rescan and clock-gate work instances

2011-04-27T23:16:12+00:00

Currently there is a race in the MMC core between a card-detect
rescan work and the clock-gating work, scheduled from a command
completion. Fix it by removing the dedicated clock-gating mutex
and using the MMC standard locking mechanism instead.

mmc: tmio_mmc: Move some defines into a shared header

2011-03-26T19:58:50+00:00

Also add TMIO_BBS.

This allows these defines to also be used by zboot.

mmc: tmio: convert the SDHI MMC driver from MFD to a platform driver

2011-03-25T14:39:23+00:00

On sh-mobile platforms the SDHI driver was using the tmio_mmc SD/SDIO
MFD cell driver. Now that the tmio_mmc driver has been split into a
core and a separate MFD glue, we can support SDHI natively without the
need to emulate an MFD controller. This also allows to support systems
with an on-SoC SDHI controller and a separate MFD with a TMIO core.

mmc: Add MMC_PROGRESS_*

2011-03-24T16:24:57+00:00

This is my second attempt to make this enum generally available.
The first attempt added MMCIF_PROGRESS_* to include/linux/mmc/sh_mmcif.h.
However this is not sufficiently generic as the enum will be
used by SDHI boot code.

mmc: dw_mmc: fix suspend/resume operation

2011-03-17T19:35:20+00:00

This patch is related to re-init processing on suspend/resume.

When card is resuming, some register is reset.  If card is removable,
maybe controller should be rescan for card.  But if assume card is
non-removable, need to restore the old value at registers.

We store the value of FIFOTH at probe time and then restore it in
dw_mci_resume().

mmc: dw_mmc: add quirks for unreliable card detect, and capabilities

2011-03-17T19:35:18+00:00

This patch adds quirks and capabilities to platdata.

Some cards don't use the CDn pin; in that case, we assume the card's
inserted. Some boards need other capabilities. So, we add capabilities
in the board's platdata.

mmc: core: export function mmc_do_release_host()

2011-03-17T19:35:11+00:00

When using mmc_try_claim_host the corresponding release
function is mmc_do_release_host, which then also must
be exported.
