   4 Subject: [PATCH] ARM: dts: NSP: Fix MX65 MDIO mux warnings
   5
   6 The naming of this node is based upon that of the initial EA9500 dts[1].
   7 However this does not conform with the mdio-mux format, yielding the
   8 following message when running dtbs_check:
   9 mdio-mii-mux: $nodename:0: 'mdio-mii-mux' does not match '^mdio-mux[\\-@]?'
  10
  11 Secondly, this node should be moved to within the axi node and given the
  12 appropriate unit address. This also requires exposing the axi node via a
  13 label in bcm-nsp.dtsi. This fixes the following warning:
  14 Warning (unit_address_vs_reg): /mdio-mii-mux: node has a reg or ranges property, but no unit name
