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. Signed-off-by: Alexey Dobriyan

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. Signed-off-by: Adrian Hunter Acked-by: Matt Fleming Cc: Ian Molton Cc: "Roberto A.

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.

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).

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(). Signed-off-by: Thomas Petazzoni Signed-off-by: Pierre Ossman
