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.

Add the required read/write_raw functions to the tsl2563_info_no_irq data
structure. This structure is used insted of tsl2563_info when the I2C client
has no IRQ.
The absence of these functions causes a panic when reading or writing the
created sysfs files.

Add a wrapper for this driver around the IIO_CHAN() wrapper to make channel
parameters more readable. This fixes a panic caused by the info_masks being
accidentally passed in as channel2 parameters which easily surpass the size
of the iio_modifier_names_light array.

In the error handling, it dereferences "st" before it has been

Add IIO_OUT type for DAC like devices
In case of IIO_OUT make sure the channel device attribute is writable
Ideally we add a flag to iio_chan_spec that tells the core that
the channel device attribute is writable...

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.
