active-semi,chglev-gpios
See: Documentation/devicetree/bindings/gpio/gpio.txt

Here and in rest of properties - no underscores but hyphens. The name
suggests that this is a value... but this is a boolean?

I think adding units suffix in binding is preferred. so "-microvolt"?

Best regards,

Hi Krzysztof,

Thank you for your so much feedback.

I will change it in next version.
