Subject: arm64: tegra: smaug: Add usb-role-switch support
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dfa93788dd8b2f9c59adf45ecf592082b1847b7b;p=thirdparty%2Fkernel%2Flinux.git

arm64: tegra: smaug: Add usb-role-switch support

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.
