mmc: fix incorrect interpretation of card type bits

2010-03-24T23:31:21+00:00

In the extended CSD register the CARD_TYPE is an 8-bit value of which the
upper 6 bits were reserved in JEDEC specifications prior to version 4.4.
In version 4.4 two of the reserved bits were designated for identifying
support for the newly added High-Speed Dual Data Rate.  Unfortunately the
mmc_read_ext_csd() function required that the reserved bits be zero
instead of ignoring them as it should.

This patch makes mmc_read_ext_csd() ignore the CARD_TYPE bits that are
reserved or not yet supported.  It also stops the function jumping to the
end as though an error occurred, when it is only warns that the CARD_TYPE
bits (that it does interpret) are invalid.

sdio: introduce API for special power management features

2010-03-06T19:26:36+00:00

This patch series provides the core changes needed to allow SDIO cards to
remain powered and active while the host system is suspended, and let them
wake up the host system when needed.  This is used to implement
wake-on-lan with SDIO wireless cards at the moment.  Patches to add that
support to the libertas driver will be posted separately.

This patch:

Some SDIO cards have the ability to keep on running autonomously when the
host system is suspended, and wake it up when needed.  This however
requires that the host controller preserve power to the card, and
configure itself appropriately for wake-up.

There is however 4 layers of abstractions involved: the host controller
driver, the MMC core code, the SDIO card management code, and the actual
SDIO function driver.  To make things simple and manageable, host drivers
must advertise their PM capabilities with a feature bitmask, then function
drivers can query and set those features from their suspend method.  Then
each layer in the suspend call chain is expected to act upon those bits
accordingly.

sdio: add quirk to clamp byte mode transfer

2010-03-06T19:26:36+00:00

Some SDIO cards expect byte transfers not to exceed the configured block
transfer size.  Add a quirk to that effect.

Patches to make use of this quirk will be sent separately.

wimax/iwmc3200: add new sdio device ID to support iwmc3200 2.5GHz sku

2009-10-19T06:55:59+00:00

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.

headers: remove sched.h from interrupt.h

2009-10-11T18:20:58+00:00

After m68k's task_thread_info() doesn't refer to current,
it's possible to remove sched.h from interrupt.h and not break m68k!
Many thanks to Heiko Carstens for allowing this.

mmc: make SDIO device/driver struct accessors public

Especially with the PM framework, those are quite handy to have in driver

sdio: add MMC_QUIRK_LENIENT_FN0

2009-09-23T14:39:37+00:00

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).

sdio: add CD disable support

2009-09-23T14:39:36+00:00

Add support to disconnect the pull-up resistor on CD/DAT[3] (pin 1)
of the card. This may be desired on certain setups of boards,
controllers and embedded sdio devices which do not need the card's
pull-up. As a result, card detection is disabled and power is saved.
