Subject: [PATCH v5 4/4] arm64: dts: qcom: lemans-evk: Enable secondary USB controller in host mode
Enable secondary USB controller in host mode on lemans EVK Platform.
Secondary USB controller is connected to a Genesys Logic USB HUB GL3590
having 4 ports. The ports of hub that are present on lemans EVK standalone
board are used as follows:-
1) port-1 is connected to HD3SS3220 Type-C port controller.
2) port-4 is used for the M.2 E key on corekit. Standard core kit uses UART
for Bluetooth. This port is to be used only if user optionally replaces the
WiFi card with the NFA765 chip which uses USB for Bluetooth.
Remaining 2 ports will become functional when the interface plus mezzanine
board is stacked on top of corekit:
3) port-2 is connected to another hub which is present on the mezz through
which 4 type-A ports are connected.
4) port-3 is used for the M.2 B key for a 5G card when the mezz is
connected.
Mark the second USB controller as host only capable and add the HD3SS3220
Type-C port controller along with Type-c connector for controlling vbus
supply.
