Hi Team,
If we set maximum speed to "super-speed" for a SSP capable controller,
I see device mode working in SS but host mode still works in SSP. From
the yaml documentation of max-speed, I see the following:
maximum-speed:
description:
Tells USB controllers we want to work up to a certain speed.
Incase this isn't passed via DT, USB controllers should default to
their maximum HW capability.
Shouldn't this maximum speed get limited to gen1 even for host mode ?
If so, can we set LLUCTL Force_Gen1 bit if (Controller is Gen2 &&
max_speed = SuperSpeed) somewhere after GCTL core soft reset is done in
set_mode ?
The reason being, there were some compliance issues seen with SSP on
some of our targets and we wanted to drop down to Gen-1 in our targets,
but limiting maximum-speed is affecting only device mode.

Krishna,
