Hello,

Thanks for reviewing Jonathan! I did split the original patch into four
parts. I should have done it in the first place, sorry about that.

I did drop the ALS data from the buffer, as they are not really useful
anyway. I also used iio_device_claim_direct_mode as requested. But making sure
buffer and event capture are not done simultaneously is quite tricky as you
mentionned.

Thanks,

Mathieu

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.
