Subject: [PATCH v3 0/3] iio: humidity: hdc3020: add threshold events support

Based on Fix:
a69eeaad093d "iio: humidity: hdc3020: fix temperature offset" in branch
fixes-togreg

Changes in V2:
- Fix alphabetical order of includes(Christophe)
- Fix typo: change varibale name "HDC3020_R_R_RH_THRESH_LOW_CLR" to
HDC3020_R_T_RH_THRESH_LOW_CLR to match variable name pattern(Christophe)
- Add constants HDC3020_MIN_TEMP and HDC3020_MAX_TEMP for min/max threshold
inputs (Christophe)
- Change HDC3020_MIN_TEMP to -40, as stated in the datasheet(Javier)

Changes in V3:
- drop u8 register pairs and switch to 16bit defines(Jonathan)
- create helper functions to avoid code duplication(Jonathan)
- Add interrupt bindings in example
- use the decimal part for setting thresholds(Javier)
- use return in switch cases hdc3020_read_thresh(Jonathan)
- fix interrupt handler:(Jonathan)
- return IRQ_HANDLED when we get a read back failure
- take the timestamp into a local variable
- fix multiline comments(Jonathan)
- use fixed value "hdc3020" instead of dev_id in probe
- clear interrupt after registering the interrupt handler
- remove interrupt polarity

Did you compile the example? I think this will fail because you don't
have the include for IRQ_TYPE_EDGE_RISING.

Missed that one, thanks. No didn't build the documentation yet. Will do
that.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Error: Documentation/devicetree/bindings/iio/humidity/ti,hdc3020.example.dts:33.34-35 syntax error
FATAL ERROR: Unable to parse input tree

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/[email protected]

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
