regulators on gpio expander

[PierreNeumann]

Hi,

I have some dependency issues in my devicetree definition.

I have a first regulator that control the power of a gpio expander connected through I2C.

This GPIO expander control other regulators, for other devices.
It seems that all regulators declared from gpio expander try to get configured before the gpio expander is initialized.
But I need the first regulator to be initialized before the gpio expander.

What is the recommended way to implement this initialization order :

First regulator -> I2C -> GPIO expander -> other regulators ?

I'm on zephyr 2.7 from nrf Connect SDK.
