Cindy H Kao f8fc329557 wimax/iwmc3200: add new sdio device ID to support iwmc3200 2.5GHz sku
Different sdio device IDs are designated to support different intel
wimax silicon sku. The new macro SDIO_DEVICE_ID_IWMC3200_WIMAX_2G5(0x1407)
is added to support iwmc3200 2.5GHz sku.  The existing
SDIO_DEVICE_ID_IWMC3200_WIMAX(0x1402) is for iwmc3200 general sku.

Ohad Ben-Cohen 7c979ec713 sdio: add MMC_QUIRK_LENIENT_FN0
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).

Adrian Hunter eae1aeeed8 mmc: add ability to save power by powering off cards
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.

Both changes above are backward compatible with earlier
firmware versions for SD8385/SD8686.

The SDIO_DEVICE_IDs for SD8688 chip are added in
include/linux/mmc/sdio_ids.h

Haavard Skinnemoen f4b7f927b5 mmc: Add per-card debugfs support
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.)

just a single file is created, "ios", which contains information about

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_*.

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.

Pierre Ossman ad3868b2ec mmc,sdio: helper function for transfer padding
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.

Anton Vorontsov 08f80bb519 mmc: change .get_ro() callback semantics
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).

Nicolas Pitre 2342f3323c sdio: allow for mmc_claim_host to be aborted
It is sometimes necessary to give up on trying to claim the host lock,
