Subject: Re: [PATCH] usb: phy: samsung-usb2: Toggle HSIC GPIO from device tree

Hi Felipe,

This is intended to pull down a reset signal line, not to switch power
to the device. I could implement that with the regulator framework
too, but I think that would just be confusing and harder to understand
without providing any benefit. It's really just a plain old GPIO.
