2017-05-21iio: light: rpr0521 channel numbers reorderedMikko Koivunen1-20/+20

2017-05-21iio: light: rpr0521 proximity offset read/writeMikko Koivunen1-0/+52
Add sysfs read/write proximity offset feature. Offset is read/write from sensor registers. Values are proximity raw 10-bit values. After applying offset value, output values will be (measured_raw - offset_value). Output values are unsigned so offset value doesn't make output negative.

Refactor _set_power_state(), _resume() and _suspend(). Enable measurement only when needed, not in _init(). System can suspend during measurement and measurement is continued on resume. Pm turns off measurement when both ps and als measurements are disabled for 2 seconds. During off-time the power save is 20-500mA, typically 180mA.

Set sensor measurement off after probe fail in pm_runtime_set_active() or iio_device_register(). Without this change sensor measurement stays on even though probe fails on these calls.

The register mapping for the IIO driver for the Liteon Light and Proximity sensor LTR501 interrupt mode is interchanged (ALS/PS).

The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, this means that exporting the OF device ID table device aliases in the module is not needed. But in order to change how the core reports modaliases to user-space, it's better to export it.

2016-12-30iio: light: add driver for Capella CM3605Linus Walleij3-0/+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.

Currently it is presented as IIO_INTENSITY channel. There are some user spaces specifically looking for IIO_LIGHT channel.

The largest thing here is deleting an obsolete driver, drivers/misc/bh1780gli.c, as the functionality of it was replaced by an iio driver a while ago. The other fixes are things that have been reported, or reverts of broken stuff (the binder change).
