Pull staging/iio driver updates from Greg KH: "Here is the big staging and iio driver patchsets for 4.11-rc1. We almost broke even this time around, with only a few thousand lines added overall, as we removed the old and obsolete i4l code, but added some new drivers for the RPi platform, as well as adding some new IIO drivers.

Qualcomm's PM8xxx voltage XOADC

|

The Qualcomm PM8xxx PMICs contain a HK/XO ADC (Housekeeping/Crystal

oscillator ADC) encompassing PM8018, PM8038, PM8058 and PM8921.
|

|

Required properties:
|

|

- compatible: should be one of:

a reference voltage on demand. The reference voltage may vary

|

|
||||
The following required properties are standard for IO channels, see
|

iio-bindings.txt for more details:
|
||||
|

- #address-cells: should be set to <1>

and reference the proper ADC interrupt.
|

|

Required subnodes:
|

|

The ADC channels are configured as subnodes of the ADC. Since some of

them are used for calibrating the ADC, these nodes are compulsory:

|

and only need to have these reg values: they are by hardware definition
|
||||
1:1 ratio converters that sample 625, 1250 and 0 milliV and create
|
||||
an interpolation calibration for all other ADCs.
|

|

Optional subnodes: any channels other than channel 0x0c, 0x0d and
|
||||
0x0f are optional.
|
||||
|
||||
Required channel node properties:
|
||||
|
||||
- reg: should contain the hardware channel number in the range
|
||||
0 .. 0x0f (4 bits). The hardware only supports 16 channels.
|

Quicker measurements can be made by reducing the decimation ratio.
|
||||
Valid values are 512, 1024, 2048, 4096.
|
||||
If the property is not found, a default value of 512 will be used.
|
||||
|
||||
- qcom,ratiometric:
|
||||
Value type: <u32>
|
||||
Definition: Channel calibration type. If this property is specified
|
||||
VADC will use a special voltage references for channel
|

calibration. The available references are specified in the
|
||||
as a u32 value setting (see below) and it is compulsory
|
||||
to also specify this reference if ratiometric calibration
|
||||
is selected.
|
||||
|
||||
If the property is not found, the channel will be
|
||||
calibrated with the 0.625V and 1.25V reference channels, also
|
||||
known as an absolute calibration.
|
||||

Capella Microsystems CM3605
|
||||
Ambient Light and Short Distance Proximity Sensor
|
||||
|
||||
The CM3605 is an entirely analog part which however require quite a bit of
|
||||
software logic to interface a host operating system.
|
||||
|
||||
This ALS and proximity sensor was one of the very first deployed in mobile
|
||||
handsets, notably it is used in the very first Nexus One Android phone from
|
||||
2010.
|
||||
|
||||
Required properties:
|
||||
- compatible: must be: "capella,cm3605"
|
||||
- aset-gpios: GPIO line controlling the ASET line (drive low
|
||||
to activate the ALS, should be flagged GPIO_ACTIVE_LOW)
|
||||
- interrupts: the IRQ line (such as a GPIO) that is connected to
|
||||
the POUT (proximity sensor out) line. The edge detection must
|
||||
be set to IRQ_TYPE_EDGE_BOTH so as to detect movements toward
|
||||
and away from the proximity sensor.
|
||||
- io-channels: the ADC channel used for converting the voltage from
|
||||
AOUT to a digital representation.
|
||||
- io-channel-names: must be "aout"
|
||||
|
||||
Optional properties:
|
||||
- vdd-supply: regulator supplying VDD power to the component.
|
||||
- capella,aset-resistance-ohms: the sensitivity calibration resistance,
|
||||
in Ohms. Valid values are: 50000, 100000, 300000 and 600000,
|
||||
as these are the resistance values that we are supplied with
|
||||
calibration curves for. If not supplied, 100 kOhm will be assumed
