iio: adc: spmi-vadc: Changes to support different scaling
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 conversion
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.

The dgnc driver has no business creating "custom" sysfs files just for a

This is a feature for the client and server to use

Fourth set of IIO new device support, features and cleaups for the 4.10 cycle.
Probably the final set before the merge window unless things get significantly
delayed.
New device support
* STM32 ADC core
- new driver. Interesting device with up to 3 ADCs with complex triggering
options that will follow later. Note split into an 'mfd like' core that
handles the interrupt sharing etc between the various instances present and
a per ADC section that is instantiated as many times as needed.
- device tree bindings.
Cleanups and minor fixes
* st_accel
- inline per sensor data as the defines don't add any meaning and make it
much harder to check if a given sensor has the right values.
* hid-magnetometer
- sort out the associations of the associated attributes with the two types.

iio: magnetometer: separate the values of attributes based on their usage type for HID compass sensor
There are 2 usage types (Magnetic Flux and Heading data field) for HID
compass sensor, thus the values of offset, scale, and sensitivity should
be separated according to their respective usage type. The changes made
are as below:
1. Hysteresis: A struct hid_sensor_common rot_attributes is created in
struct magn_3d_state to contain the sensitivity for IIO_ROT.
2. Scale: scale_pre_decml and scale_post_decml are separated for IIO_MAGN
and IIO_ROT.
3. Offset: Same as scale, value_offset is separated for IIO_MAGN and
IIO_ROT.
For sensitivity, HID_USAGE_SENSOR_ORIENT_MAGN_FLUX and
HID_USAGE_SENSOR_ORIENT_MAGN_HEADING are used for sensivitity fields based
on the HID Sensor Usages specifications. Hence, these changes are added on
the sensitivity field.
