The AM2320 is fully compatible with the AM2315 sensor in terms of I2C
communication protocol and measurement conversions.

This patch series adds am2320 to the i2c_device_id table, creates
of_device_id table and adds both am2315 and am2320 to
trivial-devices.yml dt bindings.

v4:
- Addressed minor styling issues in driver's C code pointed by Andy Shevchenko
  (carried "Reviewed-by: Andy Shevchenko <...> from v3)
- Adapted commit message pointed by Marcelo Schmitt (carried
  "Reviewed-by: Marcelo Schmitt <...>" from v3)
- Carried Acked-by: "Krzysztof Kozlowski <...>: from v3 dt-bindings patch
  since bindings patch did not change.

Note: I carried tags from v3 because reviewers declared the tag after
pointing things that were resolved in v4 (and the dt-bindings one
because the patch did not change from v3 to v4). If this is a mistake
please let me know.

v3: [3]
- Added "aosong,am2315" and "aosong,am2320" to trivial-devices.yml.
- Added of_device_id table.
- Replaced using a constant for driver's name with chip_info struct.
- Separated code changes and dt-bindings changes in two commits.

v2: [2]
 - Generalized KConfig description text.

v1: [1]

Hi Nicolás,

Applied to the testing branch of iio.git.  I'll rebase that on rc1 once that
is available and push out as the togreg branch that linux-next picks up.
