758 * The hardware design intends this port to be hooked up in peripheral
759 * mode, so we'll hardcode it here. Some details:
760 * - SDM845 expects only a single Type C connector so it has only one
761 * native Type C port but cheza has two Type C connectors.
762 * - The only source of DP is the single native Type C port.
763 * - On cheza we want to be able to hook DP up to _either_ of the
764 * two Type C connectors and want to be able to achieve 4 lanes of DP.
765 * - When you configure a Type C port for 4 lanes of DP you lose USB3.
766 * - In order to make everything work, the native Type C port is always
767 * configured as 4-lanes DP so it's always available.
768 * - The extra USB3 port on SDM845 goes to a USB 3 hub which is then
769 * sent to the two Type C connectors.
770 * - The extra USB2 lines from the native Type C port are always
771 * setup as "peripheral" so that we can mux them over to one connector
772 * or the other if someone needs the connector configured as a gadget
773 * (but they only get USB2 speeds).
775 * All the hardware muxes would allow us to hook things up in different
776 * ways to some potential benefit for static configurations (you could
777 * achieve extra USB2 bandwidth by using two different ports for the
778 * two connectors or possibly even get USB3 peripheral mode), but in
779 * each case you end up forcing to disconnect/reconnect an in-use
780 * USB session in some cases depending on what you hotplug into the
781 * other connector. Thus hardcoding this as peripheral makes sense.
783 dr_mode = "peripheral";
786 * We always need the high speed pins as 4-lanes DP in case someone
787 * hotplugs a DP peripheral. Thus limit this port to a max of high
