2015-01-25staging: Remove the Android alarm-dev driverJohn Stultz1-41/+0
The functionality provided by the Android alarm-dev driver should now be present in the timerfd interface (thanks to Greg Hackmann and Todd Poynor). As of Lollipop, AOSP can make use of the timerfd if alarm-dev is not present (though a fixup for setting the rtc time if rtc0 isn't the backing for _ALARM clockids has been applied post-Lollipop). Thus, we should be able to remove alarm-dev from staging.

2012-11-13Revert "Staging: Android alarm: IOCTL command encoding fix"Colin Cross1-3/+1
Commit 6bd4a5d96c08dc2380f8053b1bd4f879f55cd3c9 changed the ANDROID_ALARM_GET_TIME ioctls from IOW to IOR. While technically correct, the _IOC_DIR bits are ignored by alarm_ioctl, so the commit breaks a userspace ABI used by all existing Android devices for a purely cosmetic reason. Revert it.

Fixed a bug. Data was being written to user space using an IOCTL command encoded with _IOC_WRITE access mode. Signed-off-by: Dae S. Kim <dae@velatum.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Now that alarm-dev.c uses the upstreamed alarmtimer interfaces, we can remove the otherwise unused in-kernel android alarm api.

2012-04-20staging: android-alarm: Convert ALARM_ELAPSED_REALTIME to use CLOCK_BOOTTIMEJohn Stultz1-1/+6
The ALARM_ELAPSED_REALTIME clock domain in Android pointed to the need for something similar in linux system-wide (instead of limited to just the alarm interface). Thus CLOCK_BOOTTIME was introduced into the upstream kernel in 2.6.39. This patch attempts to convert the android alarm timer to utilize the kernel's CLOCK_BOOTTIME clockid for ALARM_ELAPSED_REALTIME, instead of managing it itself.

2012-02-10staging: android-alarm: Support old drivers via preprocessor aliasingJohn Stultz1-0/+14
Older out of tree drivers that were desgined to the Android Alarm in-kernel API may not build due to the namespace collision fixed in an earlier patch. Per Arve's suggestion, this patch provides preprocessor macros that allow older drivers to build.
