| Subject: arm64: tegra: smaug: Add usb-role-switch support |
| |
| From: Diogo Ivo <diogo.ivo@tecnico.ulisboa.pt> |
| |
| [ Upstream commit dfa93788dd8b2f9c59adf45ecf592082b1847b7b ] |
| |
| The USB2 port on Smaug is configured for OTG operation but lacked the |
| required 'usb-role-switch' property, leading to a failed probe and a |
| non-functioning USB port. Add the property along with setting the default |
| role to host. |
