I have a question about the XM implementation of the LAN9514, which is used for the USB2.0 hub and Ethernet controller. I noticed the reset line on this chip (HUB_RESET) is connected to GPIO56. Is this IO used somewhere in software or the device tree to reset this device? Or is it not really being used for anything?
that should be:
I was looking at that, but the device tree only mentions GPIO147, which is a reset line for USB3320, not the LAN9514. At least as far as I can tell.
