[PATCH 22/22] arm64: dts: qcom: sc7180-trogdor: Wire up USB and DP to usb-c-connectors
Stephen Boyd
swboyd at chromium.org
Fri Feb 9 23:09:33 PST 2024
Fully describe the USB type-c and DP topology on sc7180 Trogdor devices.
Most Trogdor devices have two USB type-c ports (i.e. usb-c-connector
nodes), but quackingstick only has one. Also, clamshell devices such as
Lazor have a USB webcam connected to the USB hub, while detachable
devices such as Wormdingler don't have a webcam, or a USB type-a
connector. Instead they have the pogo pins for the detachable keyboard.
Fully describing the topology like this will let us expose information
about what devices are connected to which physical USB connector (type-A
or type-C) and which port is connected to an external display for DP.
