01e57c5742 staging:iio:light:isl29018: Convert some of the isl29018 driver to the new iio_chan_spec framework.
Remove the driver's get_sensor_data() interfaces and replace them with
iio_chan_spec channels.  This converts 4 files to the new framework.
Driver ABI change: The intensity_infrared_raw file is now intensity_ir_raw.

6d1ad0f8aa staging: iio: light sensor: Add a calibscale file to the isl29018 light sensor driver.
Defaulting to 1, this gives a way to amplify the lux value before being
reduced by the programmed adc_bit shift.
Only support whole numbers right now.  When this driver is converted to the new
IIO_CHAN framework, it will be easy to support the framework's pseudo float.

Add illuminance0_calibscale documentation to sysfs-bus-iio-light.

d9b42c01ae iio: light sensor: Add SMBUS support to the tsl2563 driver.
This is so we can support it on x86 SMBUS adapters.

Since i2c adapters which do not provide an smbus_xfer interface fall
back to using their I2C master_xfer interface, all the i2c_master_send()
calls in this driver are changed to i2c_smbus_*() calls.
This will fail on an i2c adapter that implements a proper subset of
(SMBUS_BYTE | SMBUS_BYTE_DATA | SMBUS_WORD_DATA), but I do not see that
in any of our adapters today.

This results in a few wrapper functions that provide little additional
functionality, so remove them and call the smbus functions directly from
the general driver code.

88bc30548a IIO: ADC: New driver for AD7792/AD7793 3 Channel SPI ADC
New driver for AD7792/AD7793 3-Channel, Low Noise,
Low Power, 16-/24-Bit Sigma-Delta ADC with On-Chip In-Amp
and Reference.

The AD7792/AD7793 features a dual use data out ready DOUT/RDY output.
In order to avoid contentions on the SPI bus, it's necessary to use
spi bus locking. The DOUT/RDY output must also be wired to an
interrupt capable GPIO.

In INDIO_RING_TRIGGERED mode, this driver may block its SPI bus segment
for an extended period of time.

Changes since V1:

Use bool where applicable.
Use data buffer that lives in their own cache line.
Restructure ad7793_calibrate_all to use an array.
Use msleep.
Query REG_ID instead of doing a write/read This is a test.
Add support for unipolar mode.
Drop range attribute in favor of write scale.
Add proper locking.
Use new validate_trigger callbacks.
Use IIO_IN_DIFF for differential channels.
Change attribute naming.
Use available_scan_masks.
Some other miscellaneous cleanup (none functional changes).

I've currently squashed the vel + pos combined attribute.  If people need them
precisely paired I doubt they will get them from the sysfs interface anyway.
If that is a requirement it should come via a buffer implementation.

Note this patch leaves the completely non standard interface alone.
That will get fixed later.
