USB_H1_PWR control

Moving to new thread:

Hi Igor,

From RM:

- We are configuring EIM_D31 pad as USB_H1_PWR function.

- EIM_D31 pad is connecting to enable pad of power IC for cutting VBUS supply.

- When iMX6 detect over-current event, I am expecting EIM_D31 output high signal.

I would like to know the control procedure outputting a high signal from EIM_D31 pad with USB_H1_PWR function.

Best Regards,

Kazuma Sasaki.
