   4 Subject: [PATCH] dt/dtoverlays: Fix up base DT and overlays for
   5  updated Unicam driver
   6
   7 The upstreamed Unicam driver uses a dt property to denote how many
   8 lanes are supported by the receiver peripheral, independent of
   9 the number of lanes that the sensor wants to use. It also doesn't
  10 check the remote endpoint config for the number of lanes as that
  11 isn't the accepted way of doing things.
  12
  13 Update the base DT for the brcm,num-data-lanes property, and the
  14 overlays to define the desired number of lanes at both ends of
  15 the link.
