iio: Export OF module alias information in missing drivers
The I2C core always reports the MODALIAS uevent as "i2c:<client name"
regardless if the driver was matched using the I2C id_table or the
of_match_table. So technically there's no need for a driver to export
the OF table since currently it's not used.
In fact, the I2C device ID table is mandatory for I2C drivers since
a i2c_device_id is passed to the driver's probe function even if the
I2C core used the OF table to match the driver.
And since the I2C core uses different tables, OF-only drivers needs to
have duplicated data that has to be kept in sync and also the dev node
compatible manufacturer prefix is stripped when reporting the MODALIAS.
To avoid the above, the I2C core behavior may be changed in the future
to not require an I2C device table for OF-only drivers and report the
OF module alias. So, it's better to also export the OF table to prevent
breaking module autoloading if that happens.

In order to provide a channel name to in kernel consumers add the
datasheet names for every usable AD channel. Since the channel names
differ between i.MX23 and i.MX28, we need to separate the channel
specs.

Merge tag 'iio-for-4.3a' of git://git./linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First round of new drivers, cleanups and functionality for IIO in the 4.3 cycle.
Core and tools new stuff
* Allow explicit flush of hardware fifo by using an non blocking read.
This is needed to support some of the Android requirements for HW fifo
devices - also makes sense generally and clarifies a corner of the ABI.
* Add some missing modifier names. Mostly these exist for weird and
wonderful event types, but should still be present in the name array.
* Update iio_event_monitor to cope with new channel types.
* generic_buffer gains support for single byte scan elements (no idea
how this never got implemented before!)
New device support
* ROHM rpr0521 light and proximity sensor driver.
* bmc150 gains bmc156 support.
* ms5611 gains ms5607 temperature and pressure sensor support.
Driver functionality
* inv-mpu - add scale_available attributes to aid userspace in
configuring these devices.
* isl29125 - add scale_available attributes.
* stk8ba50 - sampling frequency control, triggered buffer support.
* stk8312 - sampling frequency control, triggered buffer support.
* cc10001 - ensure ADC powered up at probe time if shared by non linux
running CPUs.
* bmc150-magn - decouple the buffer and trigger allowing other triggers
to be used to drive this device's sampling.
Documentation
* Add some previously missed *scale_available attributes to the ABI docs.
Cleanups
* Clarify some crazy naming in iio_triggered_buffer_setup that seems to
have somehow ended up backwards (dates back a long way). Avoid the top
half and bottom half naming entirely given we are how dealing with a
handler and a thread in all cases.
* Tools cleanup including coding style, variable naming improvements, also
a new sanity check on a full event having been read.
* stk8ba50 - replace the scale table with a struct for clarity. Also suspend
the sensor if an error occurs in init.
* hid-sensor-prox - drop uneeded line break.
* mma9551 - use size in words for word read / write avoiding accidental
sending of an odd number of bytes.
* mma9553 - fix code alignment and document the use of a mutex.
* light/Kconfig - typo fix in commment.
* cm3323 - don't eat an error value, replace an unneeded local variable with
a generic local variable with the same use, add some blank lines for clarity.
* pressure/Kconfig - typo in Measurement Specialties name.
* bmc150-accel - actually use a mask definition rather than repeating the
value inline, code style cleanup.
* adc/Kconfig - general help description cleanup.
* ssp_sensors - drop redundant spi driver bus initialization (done in the
spi core)
* tmp006 - use genmask rather than hand generated masks.
* ms5611 - drop IIO_CHAN_INFO_SCALE as this driver provides a processed
output and as such the read only scale adds nothing useful.
* kxcjk-1013, adf4350, dummy - drop unwanted blank lines.
* Drop all owner assignments from i2c_drivers and this is done in the
i2c core.
