as6200 is a temperature sensor with a range between -40°C to
125°C degrees and an accuracy of ±0.4°C degree between 0
and 65°C and ±1°C for the other ranges.

Changes in v4:
  - Add chips that support interrupt
Changes in v3:
  - Enable interrupt property conditionally based on the chips that
    support it.
  - Fix alignment for the added example
Changes in v2:
  - Incorporate as6200 into lm75 bindings

Applied. Side note below.

Apparently checkpatch doesn't like this way of pointing to a datasheet anymore
and reacts with a warning, demanding the use of Link: or similar.
I don't think this is appropriate, so I guess we see the first instance of
to-be-ignored checkpatch warnings ins the hwmon subsystem.

Ah, no, this was a tag in the commit message, which is indeeed inappropriate.
I dropped it from the commit.
