   4 Subject: ARM: dts: imx53: Fix LDB OF graph warning
   5
   6 From: Rob Herring <robh@kernel.org>
   7
   8 [ Upstream commit 77dd4bd0c0db8e4856e7abc2192f126e226e14c5 ]
   9
  10 Single child nodes in OF graph don't need an address and now dtc will
  11 warn about this:
  12
  13 Warning (graph_child_address): /soc/aips@50000000/ldb@53fa8008/lvds-channel@0: graph node has single child node 'port@0', #address-cells/#size-cells are not necessary
  14
  15 Since the LDB should always have an output port, fix the warning by
  16 adding the output port, 2, to the DT.
