+ * - The only source of DP is the single native Type C port.
+ * - On cheza we want to be able to hook DP up to _either_ of the
+ * two Type C connectors and want to be able to achieve 4 lanes of DP.
+ * - When you configure a Type C port for 4 lanes of DP you lose USB3.
+ * - In order to make everything work, the native Type C port is always
+ * configured as 4-lanes DP so it's always available.
+ * - The extra USB3 port on SDM845 goes to a USB 3 hub which is then
+ * sent to the two Type C connectors.
+ * - The extra USB2 lines from the native Type C port are always
+ * setup as "peripheral" so that we can mux them over to one connector
+ * or the other if someone needs the connector configured as a gadget
+ * (but they only get USB2 speeds).
+ *
+ * All the hardware muxes would allow us to hook things up in different
+ * ways to some potential benefit for static configurations (you could
+ * achieve extra USB2 bandwidth by using two different ports for the
+ * two conenctors or possibly even get USB3 peripheral mode), but in
