Add new channel types support for gravity sensor. Gravity sensor provides an application-level or physical collection that identifies a device that measures exclusively the force of Earth's gravity along any number of axes.

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.

Kweh, Hock Leong authored
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. Signed-off-by:

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. Signed-off-by:

Datasheet of each device (lps331ap, lps25h, lps001wp, lps22hb) says that the pressure and temperature data is a 2's complement. I'm sending this the slow way, as negative pressures on these are pretty unusual and the nature of the fixing of multiple device introduction patches will make it hard to apply to older kernels - Jonathan.

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. Signed-off-by:

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:

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.

msleep(1~20) may not do what the caller intends, and will often sleep longer. (~20 ms actual sleep for any value given in the 1~20ms range) This is not the desired behaviour for many cases like device resume time, device suspend time, device enable time, data reading time, etc. Thus, change msleep to usleep_range for precise wakeups.
