* lib/ioremap.c: add huge I/O map capability interfacesToshi Kani2015-04-141-0/+2
| | | | | | | | | | | | | | | | | | | | | Add ioremap_pud_enabled() and ioremap_pmd_enabled(), which return 1 when I/O mappings with pud/pmd are enabled on the kernel. ioremap_huge_init() calls arch_ioremap_pud_supported() and arch_ioremap_pmd_supported() to initialize the capabilities at boot-time. A new kernel option "nohugeiomap" is also added, so that user can disable the huge I/O map capabilities when necessary. Signed-off-by: Toshi Kani <toshi.kani@hp.com> Cc: "H.

* cleancache: forbid overriding cleancache_opsVladimir Davydov2015-04-141-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, cleancache_register_ops returns the previous value of cleancache_ops to allow chaining. However, chaining, as it is implemented now, is extremely dangerous due to possible pool id collisions. Suppose, a new cleancache driver is registered after the previous one assigned an id to a super block. If the new driver assigns the same id to another super block, which is perfectly possible, we will have two different filesystems using the same id. No matter if the new driver implements chaining or not, we are likely to get data corruption with such a configuration eventually. This patch therefore disables the ability to override cleancache_ops altogether as potentially dangerous. If there is already cleancache driver registered, all further calls to cleancache_register_ops will return EBUSY. Since no user of cleancache implements chaining, we only need to make minor changes to the code outside the cleancache core.

* watchdog: enable the new user interface of the watchdog mechanismUlrich Obergfell2015-04-142-11/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the current user interface of the watchdog mechanism it is only possible to disable or enable both lockup detectors at the same time. This series introduces new kernel parameters and changes the semantics of some existing kernel parameters, so that the hard lockup detector and the soft lockup detector can be disabled or enabled individually. With this series applied, the user interface is as follows. - parameters in /proc/sys/kernel . soft_watchdog This is a new parameter to control and examine the run state of the soft lockup detector. . nmi_watchdog The semantics of this parameter have changed. It can now be used to control and examine the run state of the hard lockup detector. . watchdog This parameter is still available to control the run state of both lockup detectors at the same time. If this parameter is examined, it shows the logical OR of soft_watchdog and nmi_watchdog. . watchdog_thresh The semantics of this parameter are not affected by the patch. - kernel command line parameters . nosoftlockup The semantics of this parameter have changed. It can now be used to disable the soft lockup detector at boot time. . nmi_watchdog=0 or nmi_watchdog=1 Disable or enable the hard lockup detector at boot time. The patch introduces '=1' as a new option. . nowatchdog The semantics of this parameter are not affected by the patch. It is still available to disable both lockup detectors at boot time. Also, remove the proc_dowatchdog() function which is no longer needed.

| * | iio: add support for hardware fifoOctavian Purdila2015-03-291-0/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some devices have hardware buffers that can store a number of samples for later consumption. Hardware usually provides interrupts to notify the processor when the FIFO is full or when it has reached a certain watermark level. This helps with reducing the number of interrupts to the host processor and thus it helps decreasing the power consumption. This patch enables usage of hardware FIFOs for IIO devices in conjunction with software device buffers. When the hardware FIFO is enabled the samples are stored in the hardware FIFO. The samples are later flushed to the device software buffer when the number of entries in the hardware FIFO reaches the hardware watermark or when a flush operation is triggered by the user when doing a non-blocking read on an empty software device buffer. In order to implement hardware FIFO support the device drivers must implement the following new operations: setting and getting the hardware FIFO watermark level, flushing the hardware FIFO to the software device buffer. The device must also expose information about the hardware FIFO such it's minimum and maximum watermark and if necessary a list of supported watermark values. Finally, the device driver must activate the hardware FIFO when the device buffer is enabled, if the current device settings allows it. The software device buffer watermark is passed by the IIO core to the device driver as a hint for the hardware FIFO watermark. The device driver can adjust this value to allow for hardware limitations (such as capping it to the maximum hardware watermark or adjust it to a value that is supported by the hardware). It can also disable the hardware watermark (and implicitly the hardware FIFO) it this value is below the minimum hardware watermark. Since a driver may support hardware FIFO only when not in triggered buffer mode (due to different semantics of hardware FIFO sampling and triggered sampling) this patch changes the IIO core code to allow falling back to non-triggered buffered mode if no trigger is enabled.

New drivers * CM3323 color sensor. * MS5611 pressure and temperature sensor. New functionality * mup6050 - create mux clients for devices described via ACPI. The reasoning and approach taken in this patch are complex. Basically there is no otherway of finding out what is there than by some esoteric look ups in the ACPI data. * cm3232 - PM support * itg3200 - suspend/resume support * mcp320x - add more ADCs to the kconfig to reflect what the driver supports (this patch and the bindings got left behind when the support was added a while back). Docs / utils * ti-adc128s052 - DT bindings. * mcp3422 - DT bindings. * mcp320x - DT bindings * ABI docs for event threshold scale attributes, in_magn_offset, proximity scan_element and thresh falling/rising values for accelerometers. All elements long in use that have slipped by being explicitly documented. * Tidy up the tools previously in drivers/staging/iio/Documentation and move them out to /tools/iio. Yet another move that should have happened long ago. This time Roberta Dobrescu did the leg work. Thanks! Core Cleanups * Export userspace IIO headers. We should have done the appropriate header splitting a long time ago. Thanks to Daniel for sorting this out. * Refactor the registring of attributes for buffers to move all non-custom ones to a vector allowing easier additions to the current set in the future. Driver Cleanups * gpiod related cleanups. Make use of the additional parameter to specify initial direciton to avoid extra code. * bmc150 - Various refactorings to reduce code repitition and prepare for hardware buffer support. Some of these cleanups are good even without the new functionality. * kmx61 - direct use of index to an array avoiding a structure element which was always the index to an element in an array of that structure. * vf610 - avoid incorrect type for return from wait_for_completion_timeout. * gp2ap020a00f - use put_unaligned_le32 for slight code simplification. * ade7754 - improve error handling including suppressing some build warnings. * ade7759 - improve error handling including suppressing some build warnings. * hmc5843 - Long line and indentation fixes. Also some constifying of various constant data. * ade7854 - 80+ character line splitting. * ad2s1210 - fix wrong printf format string. * mxs-lradc - fix wrong printf format string. * ade7954-i2c - code alignment fixes and other trivial but worthwhile bits. * periodic rtc trigger - make the frequency type an unsigned int as it is always treated as such. * jsa1212 - constify struct regmap_config as it is constant. * ad7793 - typo in the MODULE_DESCRIPTION * mma9551 - check gpiod_to_irq errors. Note that this doesn't actually cause any trouble but is worth tidying up as obviously incorrect. * mlx90614 - refactor the register symbols to make it clear which reads are to RAM not PROM.

Basically, it boils down to correlating the sysfs device with the OF tree device node, so that user space can use device-tree info such as additional "location" or "label" (or whatever else we can come up with) propreties to identify a given device, or get some attributes of use about it, etc... Now, so far, we've done that in some subsystem in a fairly ad-hoc basis using "devspec" properties. For example, PCI creates them if it can correlate the probed device with a DT node. Some powerpc specific busses do that too. However, i2c doesn't and it would be nice to have something more generic since technically any device can have a corresponding device tree node. This patch adds an "of_node" symlink to devices that have a non-NULL dev->of_node pointer, the patch is pretty trivial and seems to work just fine for me.
