Hi Jonathan,
I will do the fixes and send a v3.

I have a question though:
The device has a 8 x 16-bit HW-buffer.
I want to implement the HW buffer support. Where in this driver should
I read the hardware buffer?
How is that exposed to userspace? Is it even exposed?
There is no buffer-full interrupt, It just has the latest 16 range
measurements and
latest 8 ALS measurements.

There is also a SYSTEM_HISTORY_CTRL register, which configures the HW buffer,
like setting which data to capture (ALS/RANGE) as well as turning the
buffer on/off.
Where should all this configuration be done?
Should it be default or have some sysfs attribute associated with it?

Thanks,
Abhash
