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.)

Store vendor strings found in CISTPL_VERS_1 so that function drivers
can access them.

sdio: split up common and function CIS parsing

2007-09-23T18:44:22+00:00

Add a more clean separation between global, common CIS information
and the function specific one as we need the common information in
places where no specific function is specified.

mmc: deprecate mmc bus topology

2007-05-01T11:04:18+00:00

The classic MMC bus was defined as multi card bus
system, which is reflected in the design in the MMC
layer.

When SD showed up, the bus topology was abandoned
and a star topology (one card per host) was mandated.
MMC version 4 has followed this, officially deprecating
the bus topology.

As we do not have any known users of the bus
topology we can remove support for it. This will
simplify the code and rectify some incorrect
assumptions in the newer additions.

mmc: add type field to cards

2007-05-01T11:04:16+00:00

Split out the type of card into its own field as it hardly
qualifies as a state.
