+
+maintainers:

+
+description: |
+  Fixed four-lane DisplayPort PHY for HDMI bridges, or one shared owner of
+  Type-C USB2, USB3 and DisplayPort alternate mode. DisplayPort supports RBR
+  through HBR3 without spread-spectrum clocking. The combo provider serializes
+  controller shutdown, PIPE handoff, orientation and alternate-mode changes.
+  Register resources, power domains and board tunables come from the producer.
