2013-12-26gpio: davinci: remove unused variable intc_irq_numLad, Prabhakar
As the davinci-gpio driver is migrated to use irqdomain there is no need to pass the irq base for the gpio driver. This patch removes this variable from davinci_gpio_platform_data and also the refrences from the machine file.

2013-12-24Merge tag 'iio-for-3.14b' of ↵Greg Kroah-Hartman
git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: 2nd round of new IIO drivers, features and cleanups for the 3.14 cycle. New drivers * HID inclinometer driver. * DHT11 humidity driver. Note that previous humidity drivers have been in hwmon, but no one was ever entirely happy with that, and they should find a more comfortable home in IIO (their original placement in hwmon was my fault - oops). As this is our first humidity driver, core support is also added. New features * Two of mxs-lradc channels are internally wired to a temperature sensor, make this explicit in the driver by providing the relevant temperature channel. * Add support for blocking IO on buffers. * Add a data_available call back to the interface between buffer implementations and the core. This is much cleaner than the old, 'stufftoread' flag. Implemented in the kfifo buffer. Cleanups * Last user of the old event configuration interface is converted and the old interface dropped. Nice to be rid of this thanks to Lars-Peter's hard work! * Replace all remaining instances of the IIO_ST macro with explicit filling of the scan_type structure within struct iio_chan_spec. This macro was a bad idea, that rapidly ceased to cover all elements of the structure. Miss reading of the macro arguements has led to a number of bugs so lets just get rid of it. The final removal patch is awaiting for some fixes to make their way into mainline. In a couple of drivers, no elements of scan_type were even being used so in those case, it has been dropped entirely. * Drop a couple of of_match_ptr helper uses in drivers where devicetree is not optional and hence the structures being protected by this always exist. * Fix up some cases where data was read from a device in a particular byte order, but he code placed it into a s16 or similar. These were highlighted by Sparse. * Use the new ATTRIBUTE_GROUPS macro to drop some boiler plate in the triggers core code. * ad7746 and ad7280a - stop storing buffers on the stack, giving cleaner code and possibly avoiding issues with i2c bus drivers that assume they can dma directly into the buffer. Note that this cannot currently happen as the the i2c_smbus_read_i2c_block_data function has a memcpy from the buffer actually passed to the bus driver. I missed this element of the commit message and don't think it is major enough to rebase the iio tree. * ad5791 and ad5504 stop storing buffers on the stack for an SPI driver. Unlike the i2c drivers, this is a real issue for SPI drivers which can dma directly into the buffer supplied.

It's an ugly hack working around a deadlock condition between driver core resume and block layer device removal paths through freezer which was made more reproducible by writeback being converted to workqueue some releases ago. The bug has nothing to do with libata but it's just an workaround which is easy to backport. After discussion, Rafael and I seem to agree that we don't really need kernel freezables - both kthread and workqueue. There are few specific workqueues which constitute PM operations and require freezing, which will be converted to use workqueue_set_max_active() instead. All other kernel freezer uses are planned to be removed, followed by the removal of kthread and workqueue freezer support, hopefully. Others are device-specific fixes.

2013-12-24serial: sh-sci: Rework baud rate calculationLaurent Pinchart
Computing the baud rate register value requires knowledge of the hardware sampling rate. This information is currently encoded in a baud rate calculation algorithm ID passed through platform data. However, it can be derived from the port type directly in most cases. Compute the sampling rate internally in the driver if the baud rate calculation algorithm ID isn't specified, and allow platforms to override the sampling rate through platform data in special cases (this is only required for SCIFA ports on sh7723 and sh7724, the reason needs to be investigated).

2013-12-23charger-manager: Modify the way of checking battery's temperatureJonghwa Lee
Charger-manager driver used to check battery temperature through the callback function passed by platform data. Unfortunatley, without that pre-defined callback function, charger-manager can't get battery's temperature at all. Also passing callback function through platform data ruins DT support for charger-manager. This patch mondifies charger-manager driver to get temperature of battery without pre-defined callback function. Now, charger-manager can use either of battery thermometer in fuel-gauge and ouside of battery. It uses thermal framework interface for outer thermometer if thermal fw is enabled. Otherwise, it tries to use fuel-gauge's through the power supply interface.

2013-12-22clk: add clk accuracy retrieval supportBoris BREZILLON
The clock accuracy is expressed in ppb (parts per billion) and represents the possible clock drift. Say you have a clock (e.g. an oscillator) which provides a fixed clock of 20MHz with an accuracy of +- 20Hz. This accuracy expressed in ppb is 20Hz/20MHz = 1000 ppb (or 1 ppm). Clock users may need the clock accuracy information in order to choose the best clock (the one with the best accuracy) across several available clocks. This patch adds clk accuracy retrieval support for common clk framework by means of a new function called clk_get_accuracy. This function returns the given clock accuracy expressed in ppb. In order to get the clock accuracy, this implementation adds one callback called recalc_accuracy to the clk_ops structure. This callback is given the parent clock accuracy (if the clock is not a root clock) and should recalculate the given clock accuracy. This callback is optional and may be implemented if the clock is not a perfect clock (accuracy != 0 ppb).

into drm-next drm/tegra: Changes for v3.14-rc1 This series of changes brings DRM panel support as well as initial code to register DSI hosts and peripherals and bind them to DSI drivers. The panel and DSI code are both used by the simple panel driver. The Tegra-specific changes build on top of this work to add support for various panels found on Tegra boards. New drivers enable the DSI host found on Tegra114 and a special hardware block that calibrates the pads used for DSI and CSI. The host1x and the display controller drivers gain basic Tegra124 support. To round of the new features, the DRM driver now sports a very simple PRIME implementation. In addition there are various improvements such as the host1x API being exported so that client drivers (like the Tegra DRM driver) can be built as modules. HDMI now does better power management and legacy FBDEV can now be disabled via Kconfig (though it's still enabled by default). A few sparse warnings have been squashed and various parts of the code have become more robust. * tag 'drm/for-3.14-rc1' of git://anongit.freedesktop.org/tegra/linux: (121 commits) drm/tegra: fix compile w/ CONFIG_DYNAMIC_DEBUG drm/tegra: Add PRIME support drm/tegra: Relocate some output-specific code drm/tegra: Add Tegra124 DC support drm/tegra: Fix small leak on error in tegra_fb_alloc() drm/tegra: Make legacy fbdev support optional drm/tegra: Sort reverse-dependencies alphabetically drm/tegra: Fix return value check drm/tegra: Add DSI support drm/tegra: Disable outputs for power-saving drm/tegra: Track HDMI enable state drm/tegra: Fix HDMI audio frequency typo drm/tegra: Do not export tegra_bo_ops drm/tegra: Remove spurious blank line drm/tegra: Increase compile test coverage drm/tegra: Allow the driver to be built as a module gpu: host1x: Add Tegra124 support gpu: host1x: clk_round_rate() can return a zero upon error gpu: host1x: Fix build warnings gpu: host1x: Increase compile test coverage ...

2013-12-21tracing: Add and use generic set_trigger_filter() implementationTom Zanussi
Add a generic event_command.set_trigger_filter() op implementation and have the current set of trigger commands use it - this essentially gives them all support for filters. Syntactically, filters are supported by adding 'if <filter>' just after the command, in which case only events matching the filter will invoke the trigger. For example, to add a filter to an enable/disable_event command: echo 'enable_event:system:event if common_pid == 999' > \ .../othersys/otherevent/trigger The above command will only enable the system:event event if the common_pid field in the othersys:otherevent event is 999. As another example, to add a filter to a stacktrace command: echo 'stacktrace if common_pid == 999' > \ .../somesys/someevent/trigger The above command will only trigger a stacktrace if the common_pid field in the event is 999. The filter syntax is the same as that described in the 'Event filtering' section of Documentation/trace/events.txt. Because triggers can now use filters, the trigger-invoking logic needs to be moved in those cases - e.g. for ftrace_raw_event_calls, if a trigger has a filter associated with it, the trigger invocation now needs to happen after the { assign; } part of the call, in order for the trigger condition to be tested. There's still a SOFT_DISABLED-only check at the top of e.g. the ftrace_raw_events function, so when an event is soft disabled but not because of the presence of a trigger, the original SOFT_DISABLED behavior remains unchanged. There's also a bit of trickiness in that some triggers need to avoid being invoked while an event is currently in the process of being logged, since the trigger may itself log data into the trace buffer. Thus we make sure the current event is committed before invoking those triggers. To do that, we split the trigger invocation in two - the first part (event_triggers_call()) checks the filter using the current trace record; if a command has the post_trigger flag set, it sets a bit for itself in the return value, otherwise it directly invoks the trigger. Once all commands have been either invoked or set their return flag, event_triggers_call() returns. The current record is then either committed or discarded; if any commands have deferred their triggers, those commands are finally invoked following the close of the current event by event_triggers_post_call(). To simplify the above and make it more efficient, the TRIGGER_COND bit is introduced, which is set only if a soft-disabled trigger needs to use the log record for filter testing or needs to wait until the current log record is closed. The syscall event invocation code is also changed in analogous ways. Because event triggers need to be able to create and free filters, this also adds a couple external wrappers for the existing create_filter and free_filter functions, which are too generic to be made extern functions themselves.
