2011-12-26power: Add option to log time spent in suspendColin Cross
Prints the time spent in suspend in the kernel log, and keeps statistics on the time spent in suspend in /sys/kernel/debug/suspend_time Change-Id: Ia6b9ebe4baa0f7f5cd211c6a4f7e813aefd3fa1d Signed-off-by: Colin Cross <ccross@android.com> Signed-off-by: Todd Poynor <toddpoynor@google.com>
2011-12-26PM: Change dpm watchdog to support async suspendBenoit Goby
Exclude from the watchdog the time spent waiting for children that are resumed asynchronously and time every devices, whether or not they resumed synchronously. Change-Id: I84209dfd5df72842e045096c906fd61e20e6d183 Signed-off-by: Benoit Goby <benoit@android.com>
2011-12-26PM: Dump suspend thread stack on dpm suspend timeoutBenoit Goby
When a driver takes more than 3 seconds to suspend, dump the suspend thread stack since BUG() might only dump the idle thread stack. Change-Id: If854db355fdcf3b773ea20b1b5e031def6d4b114 Signed-off-by: Benoit Goby <benoit@android.com>

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If an alarm was restarted with a value that moved it away from the head of a queue, the hrtimer would not be updated.

2011-12-26mmc: core: host: only use wakelock for detect workColin Cross
There is no need to take a wakelock for delayed lazy disable work, it will be cancelled in the suspend handler and force disabled. Only take the wakelock when the detect work is queued, and make sure to drop the wakelock if the work is cancelled.

2011-12-26Revert "mmc: subtract boot sectors from disk size for eMMC 4.3+ devices"Colin Cross
This reverts commit f0b0e4bec1e89014f3dcef4da8bcf95428cc771c. The reverted commit incorrectly calculates the size of eMMC devices in some (all?) cases. This revert may cause problems in cases where the bootloader was bug-compatible and puts a GPT partition at the incorrect end of the eMMC device. Signed-off-by: Colin Cross <ccross@android.com>

the csd sector count reported by eMMC 4.3+ cards includes the boot partition size; subtract this from the size reported to the disk since the boot partition is inaccessible (Updated by andy.green@linaro.org to use official EXT_CSD... now in mainline) Change-Id: I601b83aa0159b7aa446409ea8c945b256dd0b5b1 Signed-off-by: Gary King <gking@nvidia.com> Signed-off-by: Andy Green <andy.green@linaro.org>
2011-12-26mmc_block: Allow more than 8 partitions per cardColin Cross
Set the GENHD_FL_EXT_DEVT flag, which will allocate minor numbers in major 259 for partitions past disk->minors. Also remove the use of disk_devt to determine devidx from md->disk. md->disk->first_minor is always initialized from devidx and can always be used to recover it.

A card driver can now specify that the underlying bus should *not* auto-resume with the rest of the system.

2011-12-26sdhci: Always pass clock request value zero to set_clock host opTodd Poynor
To allow the set_clock host op to disable the SDCLK source when not needed, always call the host op when the requested clock speed is zero. Do this even if host->clock already equals zero, because the SDHCI driver may set that value (without calling the host op) to force an update at the next (non-zero-speed) call.

Lower the default time at which a higher speed is allowed to run before lowering based on lower CPU load from 80ms to 20ms. Most Android devices should trade power for performance here, although tablets and non-battery-powered devices may want to override this default.
