* iio: core: Add devm_ APIs for iio_channel_{get,release}_allLaxman Dewangan2016-04-192-0/+62
| | | | | | | | | | | | | | | | | | Some of kernel driver uses the IIO framework to get the sensor value via ADC or IIO HW driver. The client driver get iio channel by iio_channel_get_all() and release it by calling iio_channel_release_all(). Add resource managed version (devm_*) of these APIs so that if client calls the devm_iio_channel_get_all() then it need not to release it explicitly, it can be done by managed device framework when driver get un-binded. This reduces the code in error path and also need of .remove callback in some cases. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

* iio: tools: generic_buffer: auto-enable channelsLinus Walleij2016-04-192-4/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If no channels are enabled when we run generic_buffer on a device, add a command-line option to just enable all of them, run the sampling and disable them all again afterwards.

* iio: st_sensors: support open drain modeLinus Walleij2016-04-197-0/+61
| | | | | | | | | | | | | | | | | | | Some types of ST Sensors can be connected to the same IRQ line as other peripherals using open drain. Add a device tree binding and a sensor data property to flip the right bit in the interrupt control register to enable open drain mode on the INT line. If the line is set to be open drain, also tag on IRQF_SHARED to the IRQ flags when requesting the interrupt, as the whole point of using open drain interrupt lines is to share them with more than one peripheral (wire-or).

* iio: st_sensors: verify interrupt event to statusLinus Walleij2016-04-196-0/+32
| | | | | | | | | | | | | | | | | | This makes all ST sensor drivers check that they actually have new data available for the requested channel(s) before claiming an IRQ, by reading the status register (which is conveniently the same for all ST sensors) and check that the channel has new data before proceeding to read it and fill the buffer. This way sensors can share an interrupt line: it can be flaged as shared and then the sensor that did not fire will return NO_IRQ, and the sensor that fired will handle the IRQ and return IRQ_HANDLED.

* iio: st_sensors: read each channel individuallyLinus Walleij2016-04-191-50/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | The current buffer read code tries to optimize reads from the sensor data registers by issuing a single read operation across all the indata registers. This doesn't work: when the LIS331DL accelerometer sensor is configured to open drain, active low interrupt mode, this will just clear the XDA (X-axis data available) bit in the STATUS_REG register (0x27), while YDA, ZDA and even ZYXDA remain set to 1, and the internal logic of the sensor holds the DRDY (INT1) line asserted (the value of the status register is 0xee). If we instead issue one read operation per enabled channel (X, Y, Z) things start working and we can use open drain and active low interrupts. Note that a backported patch fixing this issue will be heading via the fixes branch but changes in this file already in staging-next will make that patch 'look' rather different. The code in here is the correct one when that clash hits.

* android,lowmemorykiller: Don't abuse TIF_MEMDIE.Tetsuo Handa2016-04-042-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, lowmemorykiller (LMK) is using TIF_MEMDIE for two purposes. One is to remember processes killed by LMK, and the other is to accelerate termination of processes killed by LMK. But since LMK is invoked as a memory shrinker function, there still should be some memory available. It is very likely that memory allocations by processes killed by LMK will succeed without using ALLOC_NO_WATERMARKS via TIF_MEMDIE. Even if their allocations cannot escape from memory allocation loop unless they use ALLOC_NO_WATERMARKS, lowmem_deathpending_timeout can guarantee forward progress by choosing next victim process. On the other hand, mark_oom_victim() assumes that it must be called with oom_lock held and it must not be called after oom_killer_disable() was called. But LMK is calling it without holding oom_lock and checking oom_killer_disabled. It is possible that LMK calls mark_oom_victim() due to allocation requests by kernel threads after current thread returned from oom_killer_disabled(). This will break synchronization for PM/suspend. This patch introduces per a task_struct flag for remembering processes killed by LMK, and replaces TIF_MEMDIE with that flag. By applying this patch, assumption by mark_oom_victim() becomes true.

New core support * UV light modifier (for intensity) * UV light index channel type. New device support * hp206c barometer and altimeter - new driver. * mcp4131 potentiometer - new driver supporting lots of parts from Microchip. * mma8452 - FXLS8471Q support - NXP LPC18XX SOC ADC - new driver. - NXP LPC18XX SOC DAC - new driver. - rockchip_saradc - support rk3399 * st accel - h3lis331dl support Staging driver removals * adis16204 - obsolete part making it hard to get parts to test the driver in order to clean it up. * adis16220 - obsolete part making it hard to get the parts test the driver in order to clean it up. Features * core - convenience functions to claim / release direct access to the device. Makes more consistent handling of this corner easier. Used in ad7192 driver. * ak8975 - power regulator support. * at91-sama5d2 - differential channel support. * mma8452 - runtime pm support - drop device specific autosleep and use the runtime pm one instead. * ms5611 - DT bindings - oversampling ratio support Cleanups and minor fixes * MAINTAINERS - Peter got married - hence name change! * Documentation - Fix a typo in in_proximity_raw description. - Add some missing docs for iio_buffer_access_funcs. * Tools - update iio_event_monitor names to match new stuff. - make generic_buffer look for triggers ending in -trigger as we let these in for a number of drivers a long time back and now it is a fairly common option. Drivers * staging wide - convert bare unsigned usage to unsigned int to comply with coding style. * non staging wide: - since boiler plate gpio handling of interrupts has been moved into the ACPI core we don't need to include gpio/consumer.h in a load of drivers so drop it. * ad7606 - fix an endian casting sparse warning. * ak8975 - fix a possible unitialized warning from gcc. - drop and unused field left over from earlier cleanups - fix a missing regulator_disable on exit. * at91-sama5d2 - typo and indentation - missing IOMEM dependency. - cleanup mode register usage by avoidling erasing whole thing when changing the sampling frequency. * bmc150 - use the core demux and available_scan_masks to simplify buffer handling - optimize the transfers in the trigger handler now we have a magic function to emulate bulk reads (under circumstances met here). This matters with some rather dumb i2c adapters in particular. - use a single regmap_conf for all bus types as they were all the same. * bmg160 - use the core demux and available_scan_masks to simplify the buffer handling - optimize the transfers in the trigger handler now we have a magic funciton to emulate bulk rads (under circumstances met here). - drop gpio interrupt probing from the driver (ACPI) as now handled by the ACPI core. * ina2xx-adc - update the CALIB register when RShunt changes. - fix scale for VShunt - in reality this error canceled out when used. * isl29028 - use regmap to retrieve the struct device instead of carrying a second copy of it around. * kxcjk-1013 - use core demux - optimize i2c transfers in the trigger handler. * mcp4531 - refactor to use a pointer to access model parameters instead of indexing into the array each time. * mma8452 - style fixes - avoid swtiching to active whenever the config changes - add missin i2c_device_id for mma8451 * mpu6050 - fix possible NULL dereference. - fix the name / chip_id used when ACPI used (otherwise reports as NULL). * ms5611 - fix a missing regulator_disable that left the regulator on during removal. * mxc4005 - drop gpio interrupt handling for ACPI case from driver as the core now handles this case. * st-sensors - note that there are only ever a maximum of 3 axis on current st-sensors so just allocate a fixed sized buffer big enough for that. * tpl0102 - change the i2c_check_functionality condition to bring it inline with other IIO users as EOPNOTSUPP. * tsl2563 - replace deprecated flush_scheduled_work

| | | | | | | | | | | | | | | | | | | | | | | | bmc150_i2c_regmap_conf is defined three times (in bmc150-accel-core.c, bmc150-accel-i2c.c and and bmc150-accel-spi.c), although the definition is the same. Use one common definition for bmc150_i2c_regmap_conf in all included files. Signed-off-by: Irina Tirdea <irina.tirdea@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

| | | | | | | | | | | | | | | | The scale would result in uV instead of expected mV. Mostly cosmetic, since the value of 'Power' was computed OK. Signed-off-by: Marc Titinger <marc.titinger@baylibre.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
