* iio: vcnl4000: add support for VCNL4200Tomas Novotny2018-07-291-2/+3
| | | | | | | | | | | | | | | | VCNL4200 is an integrated long distance (up to 1500mm) proximity and ambient light sensor. The support is very basic. There is no configuration of proximity and ambient light sensing yet. Only the reading of both measured values is done. The reading of ambient light and proximity values is blocking. If you request a new value too early, the driver waits for new value to be ready. Signed-off-by: Tomas Novotny <tomas@novotny.cz> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

* iio: light: add driver for Capella CM3605Linus Walleij2016-12-301-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a driver for the Capella Microsystems CM3605 Ambient Light Sensor and proximity sensor. This is a pretty simple entirely analog device that is interfaced with the target system using the POUT (proximity out) and AOUT (ambient light out) signals. The POUT signal is a simple high/low signal that indicates whether an object is in proximity, most typically used to detect a face in front of a mobile device. The signal requires that an infrared LED is mounted next to the device, making IR light reflect off the object in proximity and triggering the POUT signal. We grab a GPIO pin to handle the POUT signal as an interrupt line and register this as an event channel for the sensor. Since the proximity sensor requires an IR LED, we add a LED trigger named "cm3605" so that the infrared LED can just associate with this trigger to be sure it is always on when the proximity sensor needs it. The AOUT is an analog voltage between 0 and 1550 mV that indicate the LUX value in the ambient light: this is orthogonal to the proximity sensor functionality. Since this analog voltage needs to be converted into a digital value, the driver grabs an IIO channel named "aout" associated with the device. This patch created a combined ALS and proximity sensor driver. The former supports raw reads of the LUX value and the latter will generate proximity events. To integrate this properly with Linux we also add a supply regulator for the VDD pin (driving both functions) and add device tree bindings to define the RSET resistor that in turn configures the luminosity range of the ALS sensor. Since the sensor needs to be on more or less constantly, we restrict the power management to system suspend/resume: we disable the IR LED and disable the regulator for VDD on suspend and take them back up on resume.

Fixes from the pull request '4th set of IIO fixes for the 4.2 cycle'. * Poll functions for both event chardev and the buffer one were returning negative error codes (via a positive value). * A recent change to lsiio adding some error handling that was wrong and stopped the tool working. * bmg160 was missing some dependencies in Kconfig * berlin2-adc had a misshandled register (wrote a value rather than a bitmap) New device support * TI opt3001 light sensor * TXC PA12 ALS and proximity sensor. * mcp3301 ADC support (in mcp320x driver) * ST lsm303agr accelerometer and magnetometer drivers (plus some st-sensors common support to allow different WHOAMI register addresses, devices with fixed scale and allow interrupt equiped magnetometers). * ADIS16305, ADIS16367, ADIS16445IMUs (in the adis16400 driver) * ADIS16266 gyro (in the adis16260 driver) * ADIS16137 gyro (in the adis16136 driver) New functionality * mmc35240 DT bindings. * Inverse unit conversion macros to aid handing of values written to sysfs attributes. Core cleanup * Forward declaration of struct iio_trigger to avoid a compile warning. Driver cleanup / fixes * mxs-lradc - Clarify which parts are supported. - Fix spelling erorrs. - Missing/extra includes - reorder includes - add datasheet name listings for all usable channels (to allow them to be bound by name from consumer drivers) * acpi-als - add some function prefixes as per general iio style. * bmc150_magn - replace a magic value with the existing define. * vf610 - determine possible sample frequencies taking into account the electrical characteristics (defining a minimum sample time) * dht11 - whitespace - additional docs - avoid mulitple assignments in one line - Use the new funciton ktime_get_resolution_ns to cleanup a nasty trick previously used for timing. * Fix all drivers that consider 0 a valid IRQ for historical reasons. * Export I2C module alias info where previously missing (to allow autoprobing) * Export OF module alias info where previously missing. * mmc35240 - switch some variables into arrays to improve readability. * mlx90614 - define some magic numbers for readability. * bmc150_magn - expand area locked by a mutex to cover all the use of the data->buffer. - use descriptive naming for a mask instead of a magic value. * berin2-adc - pass up an error code rather that a generic error - constify the iio_chan_spec - some other little tidy ups. * stk8312 - fix a dependency on triggered buffers in kconfig - add a check for invalid attribute values - improve error handling by returning error codes where possible and return immediately where relevant - rework macro defs to use GENMASK etc - change some variable types to reduce unnecessary casting - clean up code style - drop a local buffer copy for bulk reads and use the one in data->buffer instead. * adis16400 - the adis16448 gyroscope scale was wrong. * adis16480 - some more wrong scales for various parts. * adis16300 - has an undocumented product id and serial number registers so use them. * iio_simple_dummy - fix some wrong code indentation. * bmc150-accel - use the chip ID to detect the chip present rather than verifying the expected part was there. This was in response to a wrong ACPI entry on the WinBook TW100. * mma8452 - fix _get_hp_filter_index - drop a double include - pass up an error code rather than rewriting it - range check input values to attribute writes - register defs tidy up using GENMASK and reordering them to be easier to follow. - various coding style cleanups - put the Kconfig entry in the write place (alphabetically). Tools related * Tools cleanup - drop an explicity NULL comparison, some unnecessary braces, use the ARRAY_SIZE macro, send error messages to stderr instead of dropping them in the middle of normal output. * Fix tools to allow that scale and offset attributes are optional. * More tools fixes including allowing true 32bit data (previously an overflow prevented more than 31bits) * Drop a stray header guard that ended up in a c file. * Make calc_digits static as it isn't exported or in the header. * Set ci_array pointer to NULL after free as a protection against non safe usage of the tools core code. Also convert a double pointer to a single one as the extra level of indirection was unnecessary. Docs * DocBook introduction by Daniel Baluta. Glad we are beginning to draw together some more introductory docs to suplement the various tools / examples. * Drop bytes_per_datum sysfs attribute docs as it no longer exists. * A whole load of missing / fixing of kernel-doc for the core of IIO. * Document the trigger name sysfs attribute in the ABI docs. * Minor typos in the ABI docs related to power down modes.

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.

Note a followup set dependent on patches in the recent merge windows will follow shortly. * dht11 - fix a read off the end of an array, add some locking to prevent the read function being interrupted and make sure gpio/irq lines are not enabled for irqs during output. * iadc - timeout should be in jiffies not msecs * mpu6050 - avoid a null id from ACPI emumeration being dereferenced. * mxs-lradc - fix up some interaction issues between the touchscreen driver and iio driver. Mostly about making sure that the adc driver only affects channels that are not being used for the touchscreen. * ad2s1200 - sign extension fix for a result of c type promotion. * adis16400 - sign extension fix for a result of c type promotion. * mcp3422 - scale table was transposed. * ad5686 - use _optional regulator get to avoid a dummy reg being allocate which would cause the driver to fail to initialize. * gp2ap020a00f - select REGMAP_I2C * si7020 - revert an incorrect cleanup up and then fix the issue that made that cleanup seem like a good idea.
