   1 * Qualcomm Atheros QCA8xxx switch family
   2
   3 Required properties:
   4
   5 - compatible: should be "qca,qca8337"
   6 - #size-cells: must be 0
   7 - #address-cells: must be 1
   8
   9 Subnodes:
  10
  11 The integrated switch subnode should be specified according to the binding
  12 described in dsa/dsa.txt. As the QCA8K switches do not have a N:N mapping of
  13 port and PHY id, each subnode describing a port needs to have a valid phandle
  14 referencing the internal PHY connected to it. The CPU port of this switch is
  15 always port 0.
