These bindings are somewhat lagging the state of the driver. The i2c-gate
bindings are documented elsewhere, but it seems sensible to at least have
an example and cross reference in here. SPI bindings will need to be the
subject of a future patch.

On Motorola phones like droid 4 there is a custom CPCAP PMIC. This PMIC
has ADCs that are used for battery charging and USB PHY VBUS and ID pin
detection.
Unfortunately the only documentation for this ADC seems to be the
Motorola mapphone Linux kernel tree. I have tested that reading raw and
scaled values works, but I have not used the timed sampling that the ADC
seems to support.
Let's add a minimal support for it so we can eventually provide IIO
channels for the related battery charging and USB PHY drivers.

the IIO core only for protecting device operating mode changes.
ie. Changes between INDIO_DIRECT_MODE, INDIO_BUFFER_* modes.
In this driver, mlock was being used to protect hardware state changes.
In the driver, buf_lock protects both the adis16060_spi_write() and
adis16060_spi_read() functions and both are always called in
pair. First write, then read. Refactor the code to have
one single function adis16060_spi_write_than_read() protected by
the buf_lock. This removes the need for additional locking via
mlock, so this locking is removed.

A good collection of outreachy related patches in here - mostly staging
driver cleanup. Also a fair number of patches added explicit OF device ID

- So far covers the sun4i-a10, sun5i-a13 and sun6i-a31 general purpose ADCs,
including thermal side of things.
This missed the last cycle due to my incompetence, so good to get in now,
particularly as various patches dependent on it are appearing.
* ltc2632
- new driver supporting ltc2632-l12, ltc2632-l10, ltc2632-l8, ltc2632-h12,
ltc-2632-h10, ltc-2632-h8 dacs

Merge tag 'iio-for-4.12b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
2nd set of new device support, features and cleanups for IIO in the 4.12 cycle
A good collection of outreachy related patches in here - mostly staging
driver cleanup. Also a fair number of patches added explicit OF device ID
tables for i2c drivers - a precursor to dropping (eventually) the implicit
probing.
New Device Support
* Allwinner SoC ADC.
- So far covers the sun4i-a10, sun5i-a13 and sun6i-a31 general purpose ADCs,
including thermal side of things.
This missed the last cycle due to my incompetence, so good to get in now,
particularly as various patches dependent on it are appearing.
* ltc2632
- new driver supporting ltc2632-l12, ltc2632-l10, ltc2632-l8, ltc2632-h12,
ltc-2632-h10, ltc-2632-h8 dacs
Cleanups
* Documentation
- drop a broken reference to i2c/trivial-devices
* ad2s1200
- drop & from function pointers for consistency.
* ad2s1210
- formatting fixes.
* ad7152
- octal permissions instead of symbolic.
- drop & from function pointers for consistent usage.
* ad7192
- drop & from function pointers for consistent usage.
* ad7280
- replace core mlock usage with a local lock as mlock is intended only to
protect the current device state (direct reads, or triggered and buffered)
* ad7746
- drop & from function pointers for consistent usage.

Driver uses multiple identifier names for the same task (retval, ret,
rc). It would be easier to read the code if a single task is
identified with a single name. 'ret' is the most common return value
identifier name found in the kernel tree, following the principle of
least surprise using 'ret' is a decent choice.
Rename rc -> ret
Rename retval -> ret

Comparison, equal to zero, is redundant
'if (foo == 0)' is equal to 'if (!foo)'
Typical kernel coding style is to use the shorter form.
Remove unnecessary zero comparison.

Driver uses different label forms for similar purposes. It would be
more clear if single use case has uniform label. 'out' is generic and
adds no meaning to label.
Documentation/process/coding-style.rst:
Choose label names which say what the goto does or why the goto
exists.
Rename labels so as to better describe what they do. If an execution
path only exists for the label on an error, prefix the label with
'err_'. If a non-error execution path exist do not use prefix.

Function uses goto label with no clean up code. In this case we
should just return directly.
Remove goto statement, return directly on error.
