From: Thierry Reding <treding@xxxxxxxxxx> Hi, These two patches add the USB controllers to Tegra124 and enable them on Venice2, wiring them up with the corresponding regulators. Unfortunately the USB1 VBUS regulator seems to be causing problems once enabled, causing none of the USB ports to work properly. Commenting out the gpio property for that regulator fixes things for me and I can use the webcam connected to USB2 as well as any of the peripherals on USB3. Since GPIO N.04 isn't connected to anything else, I don't understand how it could possibly influence any of the other USB busses. I wonder if perhaps this is caused by defect hardware, so it would be good if somebody could test this on a different Venice2.
