As usual we have a few new drivers: - TI LP8788 - TI OMAP USB TLL - Maxim MAX8907 - SMSC ECE1099 - Dialog Semiconductor DA9055 - A simpler syscon driver that allow us to get rid of the anatop one. Drivers are also gradually getting Device Tree and IRQ domain support. The following drivers got DT support: - palmas, 88pm860x, tc3589x and twl4030-audio And those ones now use the IRQ domain APIs: - 88pm860x, tc3589x, db8500_prcmu Also some other interesting changes: - Intel's ICH LPC now supports Lynx Point - TI's twl4030-audio added a GPO child - tps6527 enabled its backlight subdevice - The twl6030 pwm driver moved to the new PWM subsystem And finally a bunch of cleanup and casual fixes for mc13xxx, 88pm860x, palmas, ab8500, wm8994, wm5110, max8907 and the tps65xxx family." Fix up various annoying conflicts: the DT and IRQ domain support came in twice and was already in 3.6. And then it was apparently rebased.

| * mfd: Move tps65217 regulator plat data handling to regulatorAnilKumar Ch2012-08-221-15/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Regulator platform data handling was mistakenly added to MFD driver. So we will see build errors if we compile MFD drivers without CONFIG_REGULATOR. This patch moves regulator platform data handling from TPS65217 MFD driver to regulator driver. This makes MFD driver independent of REGULATOR framework so build error is fixed if CONFIG_REGULATOR is not set. drivers/built-in.o: In function `tps65217_probe': tps65217.c:(.devinit.text+0x13e37): undefined reference to `of_regulator_match' This patch also fix allocation size of tps65217 platform data. Current implementation allocates a struct tps65217_board for each regulator specified in the device tree. But the structure itself provides array of regulators so one instance of it is sufficient.

A lot of activities this round including considerable API and behavior cleanups. * delayed_work combines a timer and a work item. The handling of the timer part has always been a bit clunky leading to confusing cancelation API with weird corner-case behaviors. delayed_work is updated to use new IRQ safe timer and cancelation now works as expected. * Another deficiency of delayed_work was lack of the counterpart of mod_timer() which led to cancel+queue combinations or open-coded timer+work usages. mod_delayed_work[_on]() are added. These two delayed_work changes make delayed_work provide interface and behave like timer which is executed with process context. * A work item could be executed concurrently on multiple CPUs, which is rather unintuitive and made flush_work() behavior confusing and half-broken under certain circumstances. This problem doesn't exist for non-reentrant workqueues. While non-reentrancy check isn't free, the overhead is incurred only when a work item bounces across different CPUs and even in simulated pathological scenario the overhead isn't too high. All workqueues are made non-reentrant. This removes the distinction between flush_[delayed_]work() and flush_[delayed_]_work_sync(). The former is now as strong as the latter and the specified work item is guaranteed to have finished execution of any previous queueing on return. * In addition to the various bug fixes, Lai redid and simplified CPU hotplug handling significantly. * Joonsoo introduced system_highpri_wq and used it during CPU hotplug. There are two merge commits - one to pull in IRQ safe timer from tip/timers/core and the other to pull in CPU hotplug fixes from wq/for-3.6-fixes as Lai's hotplug restructuring depended on them." Fixed a number of trivial conflicts, but the more interesting conflicts were silent ones where the deprecated interfaces had been used by new code in the merge window, and thus didn't cause any real data conflicts. Tejun pointed out a few of them, I fixed a couple more. * 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: (46 commits) workqueue: remove spurious WARN_ON_ONCE(in_irq()) from try_to_grab_pending() workqueue: use cwq_set_max_active() helper for workqueue_set_max_active() workqueue: introduce cwq_set_max_active() helper for thaw_workqueues() workqueue: remove @delayed from cwq_dec_nr_in_flight() workqueue: fix possible stall on try_to_grab_pending() of a delayed work item workqueue: use hotcpu_notifier() for workqueue_cpu_down_callback() workqueue: use __cpuinit instead of __devinit for cpu callbacks workqueue: rename manager_mutex to assoc_mutex workqueue: WORKER_REBIND is no longer necessary for idle rebinding workqueue: WORKER_REBIND is no longer necessary for busy rebinding workqueue: reimplement idle worker rebinding workqueue: deprecate __cancel_delayed_work() workqueue: reimplement cancel_delayed_work() using try_to_grab_pending() workqueue: use mod_delayed_work() instead of __cancel + queue workqueue: use irqsafe timer for delayed_work workqueue: clean up delayed_work initializers and add missing one workqueue: make deferrable delayed_work initializer names consistent workqueue: cosmetic whitespace updates for macro definitions workqueue: deprecate system_nrt[_freezable]_wq workqueue: deprecate flush[_delayed]_work_sync() ...

Mark them deprecated and convert all users to flush[_delayed]_work(). If you're cc'd and wondering what's going on: Now all workqueues are non-reentrant and the regular flushes guarantee that the work item is not pending or running on any CPU on return, so there's no reason to use the sync flushes at all and they're going away. This patch doesn't make any functional difference.

In other words, that each node providing regulator init data should be named after the type of object it represented ("regulator") and hence that some other property was required to indicate which regulator the node described ("regulator-compatible"). In turn this led to multiple nodes having the same name, thus requiring node names to use a unit address to make them unique, thus requiring reg properties within the nodes and However, subsequent discussion indicates that the rules I was asserting only applies to standardized bus nodes, and within a device's own node, the binding can basically do anything sane that it wants. Hence, this change deprecates the register-compatible property, and instead uses node names to replace this functionality. This greatly simplifies the device tree content, making them smaller and more legible. The code is changed such that old device trees continue to work.

The original driver was written by: * Gyungoh Yoo <jack.yoo@maxim-ic.com> Various fixes and enhancements by: * Jin Park <jinyoungp@nvidia.com> * Tom Cherry <tcherry@nvidia.com> * Prashant Gaikwad <pgaikwad@nvidia.com> * Dan Willemsen <dwillemsen@nvidia.com> * Laxman Dewangan <ldewangan@nvidia.com> During upstreaming, I (swarren): * Converted to regmap. * Allowed probing from device tree. * Reworked the regulator driver to be represented as a single device that provides multiple regulators, rather than as a device per regulator. * Replaced many regulator ops with standard functions. * Added ability to specify supplies for each regulator. * Removed the WLED regulator. If/when we expose this in the driver, it should be a backlight object not a regulator object. * Renamed from max8907c->max8907, since the driver covers at least the C and B revisions. * General cleanup.

This is probably ok because a system contains only one instance of each regulator, but it's still bad style because any driver should be written to support multiple instances of the same hardware. This patch changes the code to dynamically allocate the memory we pass to the regulator core so the table can be constant.
