This pin defaults to active high when produced by the sensor.
The property value should ensure the flags properly describe

It's out of the PR's intended scope, and the same problem occurs elsewhere so won't block on this, but:

In another PR please review all uses of similar properties in ST devicetree bindings and make this and the others you'll find an enum too, like st,iis2dlpc's drdy-int property.

@pabigot
Yes, that's a good point. I'll do it in a separate PR.
Thanks

required: false
default: 1
enum:
- 1 # drdy is generated from INT1
- 2 # drdy is generated from INT2
description: Select DRDY pin number (1 or 2).

This number represents which of the two interrupt pins
(INT1 or INT2) the drdy line is attached to. This property is not
mandatory and if not present it defaults to 1 which is the
configuration at power-up.

range:
type: int
required: false
default: 3
description: Range in g. Default is power-up configuration.
enum:
- 0 # 500mg (0.015 mg/LSB)
- 1 # 3g (0.122 mg/LSB)
- 2 # 1g (0.031 mg/LSB)
- 3 # 2g (0.061 mg/LSB)

git commit normally complains about empty last lines, not sure why it didn't here.

Looks like it's corrected in the next commit.
