Enable secondary USB controller in host mode on lemans EVK Platform.
For secondary USB Typec port, there is a genesys USB HUB GL3590 having 4
ports sitting in between SOC and HD3SS3220 Type-C port controller and SS
lines run from the SoC through the hub to the Port controller. Mark the
second USB controller as host only capable.
Add HD3SS3220 Type-C port controller along with Type-c connector for
controlling vbus supply.

You have described one port of the hub. How are other ports routed? Are
they connected to outer ports? To some other devices? Unconnected?

Hi Dmitry,
I would like to put it this way, USB HUB has 4 ports but only one port
of the hub is used between SOC and Type-C controller.
Remaining 3 ports are used by other devices.

Hi Dmitry,
For Lemans EVK standalone corekit board, there are 4 ports as follows:-
1) p1 is connected to type c port controller.
2) p4 is used for the m.2 E key (NFA765 Bluetooth) on corekit. This
isn't used on a standard core kit, only if we optionally replace the
wifi card with the NFA765 which uses USB for BT. standard kits all use
UART for BT.
Remaining 2 ports will become functional when the interface plus
mezzanine is stacked on top of corekit.
3) p2 is connected to another hub which is present on the mezz through
which 4 type-A ports are connected.
4) p3 is used for the m.2 B key for a 5G card when the mezz is connected.

Swati

Nice. Hopefully Mani patches will be landed soon and we can describe
this one properly.

Please add a comment for these two, e.g. routed to the connector ABCDEF.

Hi Dmitry,
Thanks for the review. Can we send v4 with the following changes:
Add 4 ports each to hs and ss hub nodes and link the first port to
Type-C connector and add comments for the other 3 ports. When M.2 E
conncetor comes up, we can link the second port to it in a different patch.
Let me know if the above is reasonable.

Krishna,
