But when we add second controller (which I will after SPMI node is done), this commit text would be redundant as the same file would show example for host mode as well. Regards, Krishna,

My point was that it might be not obvious that the controller isn't designated to be peripheral on a board level and can be easily switched to work as a USB host.

Enable primary USB controller on QCS8300 Ride platform. The primary USB controller is made "peripheral", as this is intended to be connected to a host for debugging use cases.
