mmc: Add CONFIG_EMBEDDED_MMC_START_OFFSET configuration

2010-05-22T02:34:57+00:00

enables platforms to specify a non-zero offset for the MBR and kernel-visible
file systems, for embedded systems which store proprietary data at the start
of the eMMC device.

mmc: core: Add deferred bus resume policy.

2010-02-08T23:08:29+00:00

A card driver can now specify that the underlying bus should *not*
auto-resume with the rest of the system. This is useful for reducing resume
latency as well as saving power when the card driver is not using the
bus. In the future, we'll add support for manual suspend

mmc: Add concept of an 'embedded' SDIO device.

2010-02-08T23:07:54+00:00

This is required to support chips which use SDIO for signaling/
communication but do not implement the various card enumeration registers
as required for full SD / SDIO cards.

mmc: sdio: Fix bug where we're freeing the CIS tables we never allocated when using EMBEDDED_SDIO
mmc: Add max_blksize to embedded SDIO data

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: add ability to save power by powering off cards

2009-09-23T14:39:33+00:00

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.

mmc: add MMC_CAP_NONREMOVABLE host capability

2009-09-23T14:39:33+00:00

eMMC's are not removable, so unsafe resume is OK always.

To permit this a new host capability MMC_CAP_NONREMOVABLE has been added
and suspend / resume updated accordingly.

mmc: allow host claim / release nesting

2009-09-23T14:39:33+00:00

This change allows the MMC host to be claimed in situations where the host
may or may not have already been claimed.  Also 'mmc_try_claim_host()' is
now exported.

mmc: add 'enable' and 'disable' methods to mmc host

2009-09-23T14:39:33+00:00

MMC hosts that support power saving can use the 'enable' and 'disable'
methods to exit and enter power saving states.  An explanation of their
use is provided in the comments added to include/linux/mmc/host.h.

MMC: regulator utilities

2009-03-31T08:56:26+00:00

Glue between MMC and regulator stacks ... verified with
some OMAP3 boards using adjustable and configured-as-fixed
regulators on several MMC controllers.

These calls are intended to be used by MMC host adapters
using at least one regulator per host.  Examples include
slots with regulators supporting multiple voltages and
ones using multiple voltage rails (e.g. DAT4..DAT7 using a
separate supply, or a split rail chip like certain SDIO
WLAN or eMMC solutions).
