[PATCH v4 0/4] iio: vcnl: Add interrupts support for VCNL4010/20.

[Mathieu Othacehe <m.othacehe@gmail.com>]

Hello,

Here's a v4 addressing Peter and Andy remarks. The most important change is
the removal of most mutex uses, as i2c accesses are already protected
by the i2c framework.

Thanks,

Mathieu

Changes from v3:
* Use i2c_smbus_read_byte_data and i2c_smbus_write_word_data
for read and write functions.
* Rename vcnl4010_prox_threshold to vcnl4010_config_threshold.
* Do not lock i2c accesses as they are already protected.
* Fix a typo in irq name.
* Do not provide ALS sampling frequency operation, as ALS data
are not buffered anymore.
* Return bool in vcnl4010_in_periodic_mode and vcnl4010_thr_enabled
functions.

Changes from v2:
* Rebase on iio testing branch.
* Remove useless test in vcnl4010_probe_trigger.

Changes from v1:
* Split into four different patches.
* Use iio_device_claim_direct_mode to protect
raw access from buffer capture.
* Requesting a sampling frequency above the limit is no longer possible.
* Inline read_isr and write_isr functions.
* Remove IIO_LIGHT data from buffer capture.
* Make sure postenable and predisable functions respect the common form.
* Do not set the trigger by default.
* Remove the devm_iio_triggered_buffer_setup top half.
