| * ALSA: pxa27x: fix ac97 warm resetMike Dunn2013-01-082-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes some code that implements a work-around to a hardware bug in the ac97 controller on the pxa27x. A bug in the controller's warm reset functionality requires that the mfp used by the controller as the AC97_nRESET line be temporarily reconfigured as a generic output gpio (AF0) and manually held high for the duration of the warm reset cycle. This is what was done in the original code, but it was broken long ago by commit fb1bf8cd ([ARM] pxa: introduce processor specific pxa27x_assert_ac97reset()) which changed the mfp to a GPIO input instead of a high output. The fix requires the ac97 controller to obtain the gpio via gpio_request_one(), with arguments that configure the gpio as an output initially driven high. Tested on a palm treo 680 machine. Reportedly, this broken code only prevents a warm reset on hardware that lacks a pull-up on the line, which appears to be the case for me.

* | ARM: drivers: remove __dev* attributes.Greg Kroah-Hartman2013-01-034-6/+6
|/ | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Devices that use spitz_pm.c will fail to resume from STR (Suspend To Ram) when the charger plug is inserted or removed when a device is in STR mode. The culprit is a misconfigured gpio line - GPIO18. GPIO18 should be configured as a regular GPIO input but it gets configured as an alternate function GPIO18_RDY. And then later in postsuspend() it gets configured as a regular GPIO18 input line. Fix this by removing the GPIO18_RDY configuration so that GPIO18 only gets configured as a regular gpio input.

| * ARM: pxa: hx4700: Fix backlight PWM device numberPaul Parsons2012-10-281-1/+7
|/ | | | | | | | | | | | | | | | | | | | | | | | | Recent changes to PXA PWM support changed the PXA27X PWM device numbering scheme. The linux-3.5 PXA PWM driver followed the hardware numbering scheme for the 4 PWMs, while the linux-3.6-rc1 PXA PWM driver has adopted a linear numbering scheme: Address Hardware 3.5 pwm_id 3.6-rc1 pwm_id 0x40b00000 PWM0 0 0 0x40b00010 PWM2 2 1 0x40c00000 PWM1 1 2 0x40c00010 PWM3 3 3 The hx4700 backlight uses PWM1 at 0x40c00000. Consequently the pwm_id must be changed from 1 to 2. This patch fixes the backlight PWM device number and at the same time moves from the legacy PWM API (pwm_id) to the new PWM API (pwm_lookup).

* ARM: config: sort select statements alphanumericallyRussell King2012-10-131-60/+60

Any time there's a long list of items (header file inclusions, kconfig entries, array initalisers, etc) and someone wants to add a new item, they *always* go and stick it at the end of the list. Guys, don't do this. Either put the new item into a randomly-chosen position or, probably better, alphanumerically sort the list. lets sort all our select statements alphanumerically. This commit was created by the following perl: while (<>) { while (/\\\s*$/) { $_ .= <>; } undef %selects if /^\s*config\s+/; if (/^\s+select\s+(\w+).*/) { if (defined($selects{$1})) { if ($selects{$1} eq $_) { print STDERR "Warning: removing duplicated $1 entry\n"; } else { print STDERR "Error: $1 differently selected\n". "\tOld: $selects{$1}\n". "\tNew: $_\n"; exit 1; } } $selects{$1} = $_; next; } if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or /^endif/ or /^endchoice/)) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } undef %selects; } print; } if (%selects) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } } It found two duplicates: Warning: removing duplicated S5P_SETUP_MIPIPHY entry Warning: removing duplicated HARDIRQS_SW_RESEND entry and they are identical duplicates, hence the shrinkage in the diffstat of two lines.

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.

It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while. Sorry for the overhead."

The number of interrupts is taken from the devicetree node. That includes the following changes: - cpu_has_ipr() was converted from an inline function to a static bool variable, so it can be set using the "marvell,intc-priority" property inside the device node of the tree. - IRQ_BASE was converted from a macro to a runtime variable so that it can be initialized dynamically from the DT init code. - irq_base() now uses pxa_irq_base and just adds an offset. Hence, there are now no compile-time fixed values used in case of DT initialization.

With the removal of the PMU reservation code and the introduction of devicetree bindings for the CPU PMU, the enumeration is no longer required. This patch removes the enumeration and updates the various CPU PMU platform devices so that they no longer pass an .id field referring to identify the PMU type.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The EETI touchscreen asserts its IRQ line as soon as it has data in its internal buffers. The line is automatically deasserted once all data has been read via I2C. Hence, the driver has to monitor the GPIO line and cannot simply rely on the interrupt handler reception. In the current implementation of the driver, irq_to_gpio() is used to determine the GPIO number from the i2c_client's IRQ value. As irq_to_gpio() is not available on all platforms, this patch changes this and makes the driver ignore the passed in IRQ. Instead, a GPIO is added to the platform_data struct and gpio_to_irq is used to derive the IRQ from that GPIO. If this fails, bail out. The driver is only able to work in environments where the touchscreen GPIO can be mapped to an IRQ. Without this patch, building raumfeld_defconfig results in: drivers/input/touchscreen/eeti_ts.c: In function 'eeti_ts_irq_active': drivers/input/touchscreen/eeti_ts.c:65:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration] Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: stable@vger.kernel.org (v3.2+) Cc: Dmitry Torokhov <dmitry.torokhov@gmail.com> Cc: Sven Neumann <s.neumann@raumfeld.com> Cc: linux-input@vger.kernel.org Cc: Haojian Zhuang <haojian.zhuang@gmail.com>
