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

[Julius Werner]

I've tried to get the 3503 driver to work in my case for quite some
time, but ultimately gave up. For me, playing around with the load
order was not enough to solve all issues. When you try to build a
permanent, clean solution for this, you should definitely also test
the case where the hub has already been initialized and configured by
firmware before the kernel booted, because that brought on another
bunch of issues for me.

I think it ultimately only works reliably when you first reset the
hub, then reset the HSIC port on the PHY side before the USB core gets
a chance to talk to it again (thus one of the drivers needs to be
directly connected to and call the other).
