Subject: [v2 PATCH] dt-bindings: watchdog: da9062-wdt: convert txt to yaml

Convert txt file to yaml.
Add a mainterner block. Took a value from dlg,da9063 PMIC.

Signed-off-by: Nik Bune <[email protected]>
---

Changes in v2:
- Updated filename to be equal to compatible value.
- Removed ">" in description fields.
- Added optional properties to the example.
- Removed reg property, as it is not present in the txt version.

This property is a boolean...

... but you say "can be 0 or 1". Does this refer to the bit value, or
the property? There are no in-kernel users of this property as far as a
quick grep shows so it is a bi hard to tell.

Otherwise, I'm happy with this.

Thanks,
Conor.

Hello, thank you for your review!

Good point.
It looks like it is related to property itself.

I checked other bindings, like https://www.kernel.org/doc/Documentation/devicetree/bindings/iio/adc/adi%2Cad7192.yaml . They have fields of type boolean with description “When this bit is set to 1”.
So I put it as boolean.

I have just checked a couple more, and looks like they are mostly uint32 types with enum, when it goes about 0, 1 bit value in a description.
$ref: /schemas/types.yaml#/definitions/uint32
enum: [0, 1]

I will update.

Thank you.

It _seems_ like the intention was for this to be an enum, now that I
re-read the description, since it is being used to override the
behaviour from the OTP.

With that changed
