* iio: Add gravity sensor supportSong Hongyan2017-01-052-13/+64
| | | | | | | | | | | | | | | | | | | | | | | | | 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. So the most of the code for accel_3d can be reused.

* 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: light: hid-sensor-als: Add duplicate IIO_LIGHT channelKweh, Hock Leong2016-12-301-3/+21
| | | | | | | | | | | | | | | There is one light sensor type defined in the sensor hub specification, which has one Illuminance field. It doesn't distinguish between ambient light sensor or color sensor. Currently it is presented as IIO_INTENSITY channel. There are some user spaces specifically looking for IIO_LIGHT channel. To satisfy such user spaces this change also add a duplicate IIO_LIGHT channel. The units of measurement of Illuminance field is Lux, so it is still compatible to IIO ABI.

* iio: st_pressure: Export sampling frequency for lps25h and lps331apMarcin Niestroj2016-12-301-0/+2
| | | | | | | | | | | | | | | | Both devices are using the same iio_chan_spec to define which settings are exported with sysfs. Both are properly configured to set/get sampling frequency for pressure and temperature. They also properly export available sampling frequencies. The only missing thing is sampling_frequency sysfs file, which allows to set/get this property from userspace. Add sampling frequency to iio channel info mask, so sampling_frequency file is properly exported using sysfs.
