+Subject: [PATCH] dt/dtoverlays: Fix up base DT and overlays for
+ updated Unicam driver
+
+The upstreamed Unicam driver uses a dt property to denote how many
+lanes are supported by the receiver peripheral, independent of
+the number of lanes that the sensor wants to use. It also doesn't
+check the remote endpoint config for the number of lanes as that
+isn't the accepted way of doing things.
+
+Update the base DT for the brcm,num-data-lanes property, and the
+overlays to define the desired number of lanes at both ends of
+the link.
