  This GPIO controller is used on the Mobileye EyeQ5 SoC. Add its
compatible to the dt-bindings. One difference is that the block as
integrated on EyeQ5 does not support sleep-mode.

You already have such property, so you are defining it second time. You
want instead if: for eyeq5-gpio making it:
then:
  properties:
    st,supports-sleepmode: false

Good catch. I hesitated between declaring the property inside an
if-statement or disabling it inside an if-statement as you show here. I
ended-up mixing those two approaches.

Wil pick the if-eyeq5-then-disable-prop solution.

Thanks for the review Krzysztof!
