It's shaping to be another fairly busy cycle. Lots more on the way! New device support * ads7950 - new driver supporting ads7950, ads7951, ads7952, ads7953, ads7954, ads7955, ads7956, ads7957, ads7958, ads7959, ads7960, and ads7961 ADCs. * cm3605 - New driver for this light sensor and proximity sensor which is an analog part with some additional digital controls. * hx711 - New driver. Core new stuff * Gravity sensor type. This is a processed datastream in which the device will try to work out which way is down. * Split the buffer.h file into two parts. One provides the interface to 'use' a buffer, the second provides the internals of the buffer functionality as needed by implementations of buffers. - Move documentation inline so as to allow use of private: tag when generating documentation. - Add some utility functions for the few things that are directly done with the buffers. - Stop exporting functions that no-one uses outside of the core code. - Push docs down by the code in the c file where they should have always been. - Fix typo in kernel-doc for buffer. - push down some includes that were previously happening implicitly. - stop enabling the timestamp of the dummy device. Features and cleanups * ad5592r - ACPI support * ad5593r -ACPI support. * ad5933 - Fix a false comment about size of a particular register. * ad7150 - replace S_IRUGO | S_IWUSR with 0644. I'm not that keen on these patches in general, but as it was nicely presented I took this one anyway. As a general rule will only take these as part of a larger driver cleanup. - don't eat an error but rather reutnr it in the write_event_config callback. * ad7606 - replace non standard range attibute with _scale * ade7753 - use usleep_range for short sleeps * ade7754 - use usleep_range for short sleeps * ade7758 - use usleep_range for short sleeps * ade7759 - use usleep_range for short sleeps * ade7854 - use usleep_range for short sleeps * adis16201 - fix description * adis16203 - fix description - fix copyright year * adis16209 - fix description * adt7316 - Add braces to arms of if else statement (for consistency) - Alignment fixes. * axp288 - Fix up an issue with accidental overwrites of data. * bmi160 - add deivce tables for i2c and spi to support correctly identifying the full dt name (including manufacturer). - device tree binding. * bmp280 - use usleep_range for short sleeps. * cm3232 - return error from cm3232_reg_init rather than eating it if the last write fails. * dummy driver - remove a semicolor found at end of a function defintition. * exynos-adc - use usleep_range for short sleeps. * hid-sensor (accel) - Add timestamp support. The hardware can provide timestamps so lets support them. If not fall back to timestamps estimated in kernel. * hid-sensor (light) - Add a duplicate ID for the light channels so as to keep existing interface whilst also using the more standard IIO interface. * hts221 - acpi probing * imx25-gcq - Add a macro call to allow this driver to be automatically loaded. * isl29028 - reorganise code to avoid deep nesting of if statements. - move chip test and default regs into a function suitable or sharing with power management code. - tidy up some code alignment. * lidar-lite-v3 - introduce compatible strings that make it clear Garmin have consideral friends. * mma8452 - avoid returning signed value when unsigned is appropriate * spmi-vadc - Update function for generic voltage conversion to take into account that different channels on this device should be handled differently. - Rework code to allow per channel voltage scaling and support the standard options for this hardware. - Fixup three minor issues with the above patches for this part. These all effect test builds rather than the native builds for the part, but good to clean them up anyway. * st_sensors - support device matching from the ACPI DST tables. - acpi based probing for accelerometers - acpi based probing for pressure sensors - Allow pressure sensors to read negative values. - Export sampling frequency for lps25h and lps331ap. - Add support for the old DT bindings from the period when these deivces were often supported through windows.

| * iio: adc: axp288: Drop bogus AXP288_ADC_TS_PIN_CTRL register modificationsHans de Goede2017-01-101-31/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some reason the axp288_adc driver was modifying the AXP288_ADC_TS_PIN_CTRL register, changing bits 0-1 depending on whether the GP_ADC channel or another channel was written. These bits control when a bias current is send to the TS_PIN, the GP_ADC has its own pin and a separate bit in another register to control the bias current. Not only does changing when to enable the TS_PIN bias current (always or only when sampling) when reading the GP_ADC make no sense at all, the code is modifying these bits is writing the entire register, assuming that all the other bits have their default value. So if the firmware has configured a different bias-current for either pin, then that change gets clobbered by the write, likewise if the firmware has set bit 2 to indicate that the battery has no thermal sensor, this will get clobbered by the write. This commit fixes all this, by simply removing all writes to the AXP288_ADC_TS_PIN_CTRL register, they are not needed to read the GP_ADC pin, and can actually be harmful.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | buffer.h supplies everything needed for devices using buffers. buffer_impl.h supplies access to the internals as needed to write a buffer implementation. This was really motivated by the mess that turned up in the kernel-doc documentation pulled in by the new sphinx docs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gravity sensor is a soft sensor, which derives value from standard accelerometer device by filtering out the acceleration which is not caused by gravity. Gravity sensor provides a three dimensional vector indicating the direction and magnitude of gravity. Typically, this sensor is used to determine the device's relative orientation in space. The units and the coordinate system is the same as the one used by the acceleration sensor. When a device is at rest, the output of the gravity sensor should be identical to that of the accelerometer. More information can be found in: http://www.usb.org/developers/hidpage/HUTRR59_-_Usages_for_Wearables.pdf Gravity sensor and accelerometer have similar channels and share channel usage ids.

| * iio: light: add driver for Capella CM3605Linus Walleij2016-12-303-0/+341
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * iio: adc: spmi-vadc: Changes to support different scalingRama Krishna Phani A2016-12-101-108/+327
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Several ADC channels are supported in PMIC which can be used to measure voltage, temperature, current etc. Different scaling can be applied on the obtained voltage to report in physical units. Scaling functionality can be different per channel. Add scaling support per channel. Every channel present in adc has an unique conversion formula for obtained voltage. Add support to report in Raw as well as in processed format. Scaling is applied when processed read is requested and is not applied when a Raw read is requested.

| * iio: adc: spmi-vadc: Update function for generic voltage conversionRama Krishna Phani A2016-12-101-24/+28
| | | | | | | | | | | | | | | | | | | | | | | | Several channels are supported in ADC of PMIC which can be used to measure voltage, temperature, current etc., Hardware provides readings for all channels in adc code. That adc code needs to be converted to voltage. Logic for conversion of adc code to voltage is common for all ADC channels(voltage, temperature, current .,etc). Implement separate function for generic conversion logic. Signed-off-by: Rama Krishna Phani A <rphani@codeaurora.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

| * staging: iio: isl29028: remove chip test and defaults from isl29028_chip_init()Brian Masney2016-12-041-20/+22
| | | | | | | | | | | | | | | | | | | | | | | | isl29028_chip_init() contains the device driver defaults and two I2C calls that detect the presence of the chip. This patch moves these into isl29028_probe() so that this function can be used by the power management runtinme in a followup patch. This patch also renames isl29028_chip_init() to isl29028_chip_init_and_power_on(). Signed-off-by: Brian Masney <masneyb@onstation.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
| * staging: iio: isl29028: remove nested if statementsBrian Masney2016-12-041-16/+14
| | | | | | | | | | | | | | | | | | | | | | There are two callers to the function isl29028_set_als_ir_mode() and both instances use a nested if statement to only change the chip state if it is not in the proper mode. This patch moves this check into the isl29028_set_als_ir_mode() function to remove the nested if statements.

| | | | | | | | | | | | | | | | | | At the end of function ad7150_write_event_config(), directly returns 0. As a result, the errors will be ignored by the callers. It may be better to return variable "ret". Signed-off-by: Pan Bian <bianpan2016@163.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
| * iio: light: fix improper return valuePan Bian2016-12-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | In function cm3232_reg_init(), it returns 0 even if the last call to i2c_smbus_write_byte_data() returns a negative value (indicates error). As a result, the return value may be inconsistent with the execution status, and the caller of cm3232_reg_init() will not be able to detect the error. This patch fixes the bug.
