2012-08-13workqueue: CPU hotplug keep idle workersMitch Luban
This change merges two patchsets. The first set, containing 6 patches, reimplements WQ_HIGHPRI to use a seperate worker_pool. gcwq->pools[0] is used for normal priority work and pools[1] for high priority. The second patchset contains 9 patches and reimplements CPU hotplug to keep idle workers. Updates workqueue CPU hotplug path to use a disassociated global_cwq, which runs as an unbound one (WQ_UNBOUND). While this requires rebinding idle workers, overall hotplug path is much simpler.

2012-07-03regmap: add support for non contiguous status to regmap-irqGraeme Gregory
In some chips the IRQ status registers are not contiguous in the register map but spaced at even spaces. This is an easy case to handle with minor changes. It is assume for this purpose that the stride for status is equal to the stride for mask/ack registers as well.

2012-07-02regulator: tps80031: support for min voltage toleranceLaxman Dewangan
Sometimes the system allow to run in less than requested minimum voltage and if this tolerance allow the regulator to set voltage in lower side range than this saves the power. For the example, if client request vmin = 975mV for regulator voltage then it sets the voltage to 987.5mv as the nearest to this desired value. The next lower side for the voltage is 974.8mv. So if system runs on tolerance of 1mv and if it request for 975mv then driver can look for minimum voltage as 975 - tolerance(1) = 974mv and possible configure 974.8mv rather than 987.5mV and so it can save the power equivalent to 12.5mV higher voltage. Support the configuration of tolerance value.

- add public APIs for power & sync-point management - all these APIs end with string _ext - all these APIs can be found in linux/nvhost.h - all these APIs take nvhost_device as first argument - all these APIs are based on the fact that host1x hardware driver is parent of all the host1x client driver - this allows clients of host1x which are outside host1x driver code to just include nvhost.h & use host1x driver interfaces - this also hides the implementation details of power & sync-point inside host1x driver code - move sync point ids for dc and nvavp to nvhost.h Bug 961009 Change-Id: I1a9ca074df87656c4d4bd246853e039a7850d56a Signed-off-by: Mayuresh Kulkarni <mkulkarni@nvidia.com> Reviewed-on: http://git-master/r/109219 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> GVS: Gerrit_Virtual_Submit
