mmc: Add mmc_vddrange_to_ocrmask() helper function

2008-12-31T17:18:13+00:00

This function sets the OCR mask bits according to provided voltage
ranges. Will be used by the mmc_spi OpenFirmware bindings.

Fix comment in include/linux/mmc/host.h

2008-10-12T09:04:34+00:00

In include/linux/mmc/host.h, it is mentionned that the callback to
know if a card is present or not is get_ro(). But it's get_cd().

mmc: Add per-card debugfs support

2008-07-26T23:26:17+00:00

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.)

mmc: Export internal host state through debugfs

2008-07-26T23:26:16+00:00

When CONFIG_DEBUG_FS is set, create a few files under /sys/kernel/debug
containing information about an mmc host's internal state. Currently,
just a single file is created, "ios", which contains information about
the current operating parameters for the bus (clock speed, bus width,
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_*.

mmc: remove multiwrite capability

2008-07-15T12:14:49+00:00

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.

mmc: fix sdio_io sparse errors

2008-07-15T12:14:48+00:00

This patch fixes sdio_io sparse errors.
This fix changes signature of API functions,
changing
unsigned char -> u8
unsigned short -> u16
unsigned long -> u32 - this was probably a bug in 64 bit platforms
