Some regulators can supply multiple voltages. To take changing voltages into account, the scale needs to be calculated on every read access. Signed-off-by:

Fix some indentation issues and separate returns by empty lines (IIO style). Also rename the channel mask in _read_raw() to mask. Signed-off-by:

A return variable is not required in _write_raw(), and dropping it reduces complexity, as well. Signed-off-by:

The regulator framework requests to balance regulator_enable() calls with regulator_disable() calls. To meet this requirement, set channels to 0 on remove, which implies a regulator_disable() call in case that channel was enabled. Signed-off-by:

Hartmut Knaack authored
This device simply uses its Vcc as reference voltage, so the same scale applies for all channels. Also offset doesn't appear to be different for any channel. Represent this by switching these two attributes to info_mask_shared_by_type. Signed-off-by:

Previous offset wasn't applied in the correct order and invalid. This patchset fixes this issue, and also has the correct scale value applied to the offset. Signed-off-by:

i2c_client struct is now only used for debugging output. We can use the device struct as well so we can remove all struct i2c_client usage. Signed-off-by:

Commit 845c8770 ("i2c / ACPI: Assign IRQ for devices that have GpioInt automatically") automatically assigns the first ACPI GPIO interrupt in client->irq, so we can remove the probing code from drivers that use only one interrupt. Signed-off-by:

Since commit dab472eb ("i2c / ACPI: Use 0 to indicate that device does not have interrupt assigned") 0 is not a valid i2c client irq anymore, so change all driver's checks accordingly. The same issue occurs when the device is instantiated via device tree with no IRQ, or from the i2c sysfs interface, even before the patch above. Signed-off-by:

Dan Carpenter reported a static checker report and after his mail I noticed that we actually return from function if positive value is obtained from i2c read. This was remainder from when code was not in separate function (which I changed during the review process). Static checker reported drivers/iio/temperature/mlx90614.c:167 mlx90614_iir_search() warn: this cast is a no-op which meant that cast before negating is useless. Dan also proposed a solution on nicer bit operation form. Also changed magic number to macro in process as that was confusing. Reported-by:Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by:

Chipset sometime updates in the middle of a reading causing it to reset the data pointer, and causing invalid reading of previous data. We can check for this invalid state by reading MSB of the resistance reading that is always zero, and by also confirming the VOC_short isn't zero. Signed-off-by:

Merge tag 'iio-for-4.4a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First round of new driver, new functionality and cleanups for IIO in the 4.4 cycle New device support * APDS9960 ALS + proximity driver * bmg160 SPI devices. * HDC100x humidity sensors * Holt HI-8435 threshold detector * mma8453Q accelerometer added to the mma8452 driver * mma86452FC and mma8653FC accelerometers added to the mma8452 driver * mxc4005 accelerometer * PulsedLight LIDAR * SensorTech VZ89x volatile organic compound sensor * UPISEMI uS5182d ALS and proximity sensors New core functionality * triggered events - use triggers to check for changes in threshold type detectors on devices with out interrupt support. First user is the holt comparator. * chemical concentration and resistance channel types. New driver functionality * vf610 - buffer support. - followup coccinelle warning fix. Core rework * buffers - break out callback buffer to own module. - move buffer implementations to a new subdirectory * percolate the error code form iio_event_getfd out to userspace rather than giving a missleading error later on. Cleanups * adddac drivers - use BIT macro where appropriate. * meter drivers - use BIT macro where appropriate. * ad7303 - add an OF match table to line up with the binding docs. * adc128s052 - add an OF match table to line up with the binding docs. * adf4350 - add an OF match table to line up with the binding docs * as3935 - add an OF match table to line up with the binding docs. * berlin2-adc - use GENMASK and BIT for masks - prevent attempting to sample multiple channels at once by moving a mutex scop - coding style cleanups * bmg150_magn - kconfig sort order was wrong - fix it. * bmg160 - use i2c regmap and drop all uses of i2c_client - separate i2c and core driver * cc10001_adc - kconfig sort order was wrong - fix it. * evgen (dummy driver helper module) - move interrupt generation to irq_work to reduce differences between the dummy driver and real hardware drivers. * hmc5843 - set the name dynamically rather than to a fixed value for one of the suported parts. - export module alias information to allow autoprobing of module. * lpc32xx - on failure to get resource or irq return -ENXIO as uppose to -EBUSY * max1027 - set .of_match_table to actually allow OF style matching. * max5821 - add MODULE_DEVICE_TABLE for OF table. * mma8452 - refactor to separate out chip specific data. - add freefall / motion interrupt source for devices that do their interrupts slightly differently. - update copywrite notice. - leave naming of events directory in sysfs to the core * mcp320x - set .of_match_table so that it can be use for OF style matching. * mlx90614 - Implement filter configuration (note the datasheet changed as a result of the driver reviews to include the values we needed ;) * opt3001 - drop .owner field as assigned by platform driver core. * si7020 - replace a bitmask on the humidity values with a more correct range check. * stk310 - improved error handling. - use BIT macro where appropriate and use the resulting defines instead of magic numbers in the code. - fix indentation * st-sensors - add debugfs register read hook * tsl4531 - fix error handling in check_id * twl6030 - fix module autoload for OF * iio-trig-sysfs - document add and remove attribute * trigger in staging - code alignment fixes. - braces on both branches of if statement if needed for one. * xilinx-xadc - push interrupts into hardirq context as there isn't much in them any more and it avoids breaking PREEMPT_RT builds due to the use of a spinlock between the hardirq and the thread. Tools * event-monitor - report unsupported events. We keep expanding what can come from drivers so give a helpful error if one turns up in an out of date userspace program. * generic-buffer - helpful message about needing to enable a channel to start the buffer.

This patch is a first stab at trying to remove structure fields from obd_export and obd structures that are only used on the server or make sense on the server. These include tracking requests in recovery, various recovery stages, lists of recovered and not yet recovered clients and so on. Also prune functions that use these fields. Signed-off-by:
